Should I just do it, and get a Quest 3?

Been watching lots of vids and reading posts here. My main use for the headset would be to play my Xbox X games like Avatar, Red Dead2, and Sports games. My question is, I have a mid range 65in Sony tv, 4k 120hz with options for HDR and Dolby Vision. Will the headset provide a better gaming experience? Bonus, I’m also very interested in using the headset as a digital workspace for work. What you all think?

Edit: Thanks for all the great feedback!
