Hello all. We are building a simple and fairly modest 1700 sq foot house from scratch in SoCal. We are using pre-built trusses and there will be significant overhang around the house. We are picking out windows and sliders at the moment and got quotes for 3 types of windows from our architect's window guy. We are going for a modern look (architect calls it modern barn), with 8ft windows/sliders. These quotes include 2-12ft wide sliders, so that really increases the cost (6k each on the higher quotes). Our quotes are as follows (uninstalled):

Milgard (thermally broken aluminum) - 11k

Marvin ultimate (fiberglass clad wood) - 28k

Weathershield contemporary (extruded aluminum clad wood) - 28k

We are limited on budget (we bought this home, expected quick DIY renovations as we had done on our previous fixer - superficial stuff - but it was in such poor shape we had to basically use existing foundation and do a new build). Even so, there is little chance that we're going with the aluminum. Our architect uses this Milgard line very often (lots of MCM style) but I saw them in show room I was not impressed, even at that cost savings. My husband and I are in our mid thirties with three children 5 and under, so I expect we will be in the house for 20+ years, so we want to get something that will last.

We may go with one of the other two options. We have a window and door schedule now. We are not yet through the permit process so we have a little more time to go and look around and get some quotes.

So.... Of those choices, which is the best in your opinion? From what I gather from reading here, Marvin will likely get higher marks but admittedly, the Weathershield look and feel great in person and initially were my favorite.

Our architect's window guy was helpful and no pressure, but I assume it's customary to get other quotes? The husband and I are planning to go "window shopping" this weekend. I'm open to all advice!
