The thing I worry about is always about cleaning. As much as I love open shelving, pot racks, rail systems, knife systems integrated into the counter, and all the various doodads, I just really experience even my 2 cubbies as dust and grease magnets.

So, I guess there's the pro and the con for me. Sorry I am not more help when it comes down to specific systems.

I have one from Lee Valley . It is very well made and quite inexpensive. Also easy to assemble. Here is a pic . I don't have all the accessories that you mention but they have them. Good luck. c

My thought is that this would not be in the hood/ cooktop area as I share the concern about grease and dirt. I was thinking more about prep area.

They are very appealing for some reason but I never have a good spot for them. I did have a short section of one (the least expensive Ikea one I think) next to my cooktop attached to the side of an oven cabinet and it was fairly useful for a few bottles, seasonings, and pot holders. Then I remodeled and put it in the garage over the laundry sink to hold stuff for dishwashing during the remodel and it was REALLY handy there. (This was a setup where I was washing dishes in a dishpan on top of a milk crate and draining them on the washing machine.)

Anyway if you've got a spot for it and stuff to hang from it, even if you decide you don't like it, the rail will still be innocuous and not bug you (especially that cool flat one!), go for it. I like the styling on the Lee Valley one but now have to check out the one you linked.

(Keep in mind this is coming from someone who just nailed a bunch of skillets to some cabinets, though...)
