Door window opinions

[novice]

I am currently doing a total frame off. I'm to the point of getting the door hardware needed to complete my new doors. I've been debating installing the one piece windows in lieu of new vent windows. I like the look personally. I have read that people have had issues with the kits sealing, operating properly, etc.. I've also read many complaints about the fitment, sealing, and alignment of new vent windows. Personal experience and reviews are much appreciated from anyone that has experience with either these options.
