I use Bazzite (https://bazzite.gg https://bazzite.gg) on my laptop since about a year. It is based on Fedora, with KDE built in and a lot of back end configurations for easy gaming that just works. It is also an immutable distro. It has been completely smooth for me, that said for Discord, I would recommend installing Vesktop as a flatpak, it is an alternative electron packaging of discord with Vencord (a plugin framework for the discord client) but more importantly it has support for screen sharing, that the official Linux discord client has but with a lot of issues.
