I have the aluminum frame windows on both my boats, which I consider to be less stylish but much more practical, so I'm basically just an interested onlooker to this discussion. But it seems to me a point made several years ago in a similar thread has been lost here.
The frameless windows were glued into the deck/cabin structure and helped to stiffen it, which also helps to stiffen the whole boat. Plexus seems a right PITA to use, but it has lasted the better part of 30 years on our old boats. And the comments about damaging gel oat when removing old portlights speaks to its tenacity as an adhesive. Sika 295uv, and the 3M equivalent, are great adhesives and sealers. (And also a PITA to use. Don't even THINK about not using the primer.) I used Sika 295 on my rebuilt hatches, and it is great for car windshields (which are bedded in rubber so the window does not crack as the car body flexes) but it remains flexible. And from the previous discussions on the list I've gotten the impression that the hull and deck flexing leads to leaks in a few years, and polycarbonate portlights held in by screws tend to get cracks at the stress points. As I said, I have no real experience with the glued in portlight solutions and I'm happy with my simple, cheap, durable, but not stylish aluminum frames. I just wanted to remind the group about why the frameless portlights were glued in by C&C in the first place.
