The Marvins are normally cheaper than the 400s around here. The 400 is a solidly built window in my opinion. Depending on what you are needing, there are options beyond just those you mentioned and perhaps they might be worth looking into.

So, I have a lot of window trim that is rotted and literally crumbling. The windows themselves also look pretty bad (the left two won't close all of the way even though i've tried to relock them). The front of the house just bakes from the sun and our AC bill in the summer is ridiculous despite the fact that we have new HVAC systems and proper attic insulation. So, if i'm going to have to replace a lot of the trim anyway, it seems to make sense to do it all at the same time. Capping the new windows and replacing rotten trim is included in the price. I've run the numbers and it's about the same cost to keep the current number of windows or change to taller/fewer number of windows. I can't figure out which will look better. I would think the tall front doors and windows would look awesome, but I'm afraid I won't know for sure until it's done.

I would not do vinyl, and I would not do double hung. The first is poor quality that doesn't last. The second is inappropriate to your house, which is very cute! I would replace with aluminum clad wood casement windows with a dark chocolate or black exterior cladding. Have you looked in to fixing your windows? Wood windows last hundreds of years with proper upkeep, IDK about windows manufactured when your house was built, though.

I would lose the shutters and just let the house be modern. The casement windows, massing, and the whole gable end are not traditional at all. At that point black windows with grey siding would work well, I would paint the window trim black as well
