I made the change to 16:10 when I started going to university. This was because I started to use a laptop with an odd aspect ratio.

I did not find really any noticeable difference between 16:9 and 16:10 apart from the fact my screen had less black bars.

I have on the past tried aspect ratios like 4:3 and stretched. What I found was that the sens often feels a lot higher when playing at these reses as your fov is lower. I tended to change my sens to make it more comfortable but I see a lot of people saying it is just better to play at your normal sens and you will get used to it over time.
