I currently run windows 10 on my main desktop PC, and also have a steam deck that I sometimes use in desktop mode instead of my desktop. With the way Windows is going, and the way Linux Gaming is dramatically improving, I might consider ditching Windows, at least for the most part, on my next PC build. What would be the best distro to use for gaming, with casual use as well? Any suggestions?
If you're using a LTS release then you should be aware that many of the programs in the repository will only get bug-fixes and security updates until the next LTS is out. You can get around this by using the Flatpak versions of those programs instead of the distribution's versions.
Nonsense. Long-term support (LTS) generally lasts until either a predetermined date or until multiple subsequent releases are out. I don't know of any that stop when the next LTS release arrives, but if such a distro exists, it is atypical.

I don't mean that the security updates will stop, I mean that you'll only get security updates. If you want to get feature-updates between LTS releases you'll need the Flatpak versions.
