I'm not really seeing anyone ask the big question here, but the obvious answer is it depends on what you want to play. If certain titles that are your preferred picks are completely unplayable on Linux for whatever reason, then it might be a deal breaker for you. Anti cheat, secure boot, DRM and a myriad of other increasingly restrictive systems are making it impossible for a lot of things to work reliably on Linux. Start with proton db, which is a useful site that can help you check if the games you like actually work on Linux, and if you're still sure, then you can safely make your decision.
