realmain:
It doesn’t hurt to try even if it’s experimental. It shouldn’t break your installation to boot into kernel 5.11. Worse comes to worst, it doesn’t boot in, you get a black screen, or you get kernel panic, etc, but it doesn’t ruin your installation, you just select a different kernel you have installed.
Currently, in stable repo, it is at 5.11.rc7 (release candidate 7). 5.11.1-1, which is full stable release is currently in testing and unstable. You can wait until it gets pushed to stable, but I personally recommend just to try the current one in Stable to see it it works!
How reliable are these experimental kernels? And regarding about gaming should i go with LTS or latest kernel? Could the latest one fix glitches and compatibility issues?
