Hello again! It's been a while. I hope you are doing well.
So.... The Xbox Game Bar screen recorder saves the files as .mp4 files. On my computer they are saved to File Explorer in the Videos > Captures folder. You can share the .mp4 file on YouTube or wherever you like.
I think it's simpler because it's pre-installed, but that's just my opinion. I like how I can easily change settings in the Settings app (like turning off recording the mouse pointer or changing the framerate). However, one negative about Game Bar captures is that it only records at up 1080p. I don't need 4k video, but some people might prefer it.
I hope this answers your question(s). If it does, you can mark this post as a suitable answer by clicking the button below.
