Dolby atmos

.

almost everyone I know prefers playing without it

It's pretty much just a gimmick, for gaming anyway. Just get a good pair of open headphones (not a headset), and leave it on stereo.

Dislike. Sounds like I'm playing in a bathroom.

it sound weird but i find that positional audio was better for me with it enabled, so i leave it on

I feel like the positional audio is better, however the sound quality sounds so distorted and unnatural. There is way too much bass, too little treble, some weapons lose their "umph" and don't feel great. It's very polarizing. In fact a lot of the time it just sounds like a fat man farting in my ear.

I keep it off.
