I have grown Cobra 2x and it does fine outside as well as in the GH. It isn't especially large fruit, not what I'd call a true slicer, but much larger than a cherry type and has a good average (not great) flavor. While it wouldn't be one of my first choices, given your limited options it is well wroth growing.

Roma in containers is very prone to BER issues but if you can keep the soil moisture levels consistent it is an ok paste-type tomato.

Sweet 100 is a huge!! plant but also produces hundreds of cherry tomatoes that are quite good.

And Lemon Boy, if you like yellow tomatoes, can be excellent.

I'm in the same zone (2b) and I grow all sorts of tomatoes, even the heirlooms that require a longer season. From your list, there appears to be a lot of cherry/small tomatoes, I've grown the Sweet 100 and it was an enormous plant that produced masses of cherry tomatoes...I prefer Sungold/Sunsugar for taste and sweetness. Big Beef is very commonly sold and would be a good choice for a general use tomato.

From your list I would narrow it down to these three (besides the basket varieties). 1) Sweet 100 has a very large habit and is very productive cherry. 2) I think Sub Arctic is a very early bush determinate. Interesting variety with medium size fruits. 3) Lemon Boy F1 is fairly early and a nice yellow variety. It has a medium size habit for us.

Thank you all for taking the time to share your thoughts
with me. I love hearing everyone’s
opinions and greatly appreciate it.

Looks like there is a decent consensus on the Sweet 100
so I will definitely give that one a try. Although,
I have to admit, the purported size of the plant intimidates me a bit. I had originally hoped to try to stick with
just determinate varieties this year but I am going to just scrap that. I will just give the Sweet 100 a 20-30 gallon
SIP to itself and invest in a sturdy staking setup.

I am not really interested in tomatoes for “slicing” I
don’t think my landlords are either; although they are very excited for cherry
tomatoes.

Any other plants I choose will be used mostly for salsa
and sauces which makes me initially lean towards planting a Roma. BER worries me but I am hoping that a SIP will
help me in keeping my soil moisture as consistent as possible.

Do you think Cobra, Lemon Boy, or Sub Arctic would work
okay for sauces?

I think Lemon Boy would
make a very interesting salsa. I can’t say whether or not I like yellow tomatoes
as I have no experience with them.

Do you think Sweet 100 would work for a sweet basil
marinara?

Our nursery always used to carry Early Girl but, for some
reason, they don’t have it this year.

We had a farmer that used to come up biweekly to sell
produce and he often had Sungolds. They
always sold out fast and really helped me start liking fresh tomatoes. (I had no idea they could taste so sweet!)

I will be haunting the local Cnd Tire and other stores
closer to planting time to see what they have and if any of it is worth paying
money for.

Unfortunately, I have no space available for starting or
nurturing plants like toms inside. I am
currently renting a small bachelor style basement suite that walks directly out
to the back yard. I have one large east
facing window but no room for any type of grow setup at the moment.

Hello all. I just
wanted to let you know of a happy-ish, maybe, development.

My local SaveOn Foods brought in some veggie plants this
week and they had a small collection of tomato plants; Brandywine (No mention
of strain just “Heirloom”), Cherokee Purple, La Roma 111, and one other that I
cannot remember the name of at this moment.

I was shopping with my landlords; they are not major
gardeners but are very excited with my ideas for the yard and are eager to
monopolize on my tomato efforts. They decided
to buy a Brandywine as their contribution to the grow effort.

I am not sure how it is going to fair as it is still
going to be about a month before it will be planted outside permanently. They are keeping it at their place, next to
an east facing window, until it can go outside.
I am not sure if that is going to be sufficient light so the Brandywine will
be a sort of experiment. From what I
have read about this ‘mater I am not getting my hopes up.

I am wondering if it is worth it to pick up one or two of
the other varieties to try or if I should just hold on to my money and wait for
the surer bet of the local nursery plants.

If the Brandywine survives I will plant it and try; Sweet
100, Roma, and Lemon Boy.

We will see what the future brings as more stores stock
up on plants. J

Brandywine is a late tomato and not a big producer for most people, although the tomatoes you will get will be delicious. I am concerned that you won't get much production to speak of in your zone.

Cherokee Purple is delicious and is mid-season around here for me. People report production from stingy to high. It's moderate-high production for me.

Re: your original list, +1 on the Sweet 100, and I'd go with Lemon Boy. Yes, you can make sauce and salsa out of it. You can make sauce with any tomato--it's just that the non-paste ones will have a higher moisture content so will require longer cooking to get the extra water out (or you can try what I do and oven roast the tomatoes first to ditch some of the moisture that way). I actually really like salsa made with yellow or orange tomatoes, personally.

The most important thing for you to consider in choosing cultivars is days-to-maturity.

With very few exceptions, most open-polinated ripen very late. In your zone, you may not get any fruit before frost with an OP.

Make your selections primarily on DTM. However, I understand that sun-artic has short DTM, but not much taste.

Don't put much money into growing Brandywine: late, few fruit, uneven ripening so that each fruit is half-ripe, half-green. Don't expect much fruit, if any.

Tiny Tim is a shade-lover. Taste is not special, but it grows where no other tomato lives. Great to put your own tomatoes in salads. Lots of tomatoes for the small size. Depending on pot size, it is 1-2 feet tall. It is happy all year even in a north window.

The sweet 100's are much smaller plants: normal height (6-8 ft here), but not nearly as wide and husky. You can grow two or more of them in the space taken by one Brandywine or Sungold.

You could probably still mail-order some Early Girls, which are more cold-tolerant than most cultivars: they start earlier and end later. You get more fruit from a plant because of EG's longer growing season, and it is great to get the ripe tomatoes late. Tolerates being potted well.

You could think about purchasing some plants online, you'd have more choices.
