One Piece glass or not?

[muddpile]

I am trying to decide between going one piece glass or not. I need a passenger window anyways (mines plexiglass siliconed in), so I was thinking about upgrading. What are the advantages to each? The way I see it, the one piece glass has less places to leak, but I've heard it tips in when you roll the window down. The factory setup has a nice look to it, but sometimes those little triangle windows can leak. My truck has no air, so the small windows providing ventilation is a bonus, but they're so noisy when open that the lowered interior temp is counteracted by a higher noise. Anyone got any more points to add? Thanks!
