I wouldn't know, I haven't played Wii sports much. The speed of your movements is tracked, so that's tougher to fake. In your case, if you'd be in The Netherlands, I'd recommend you to buy a Quest 2 at the store with the clear question if you can return it the next day if you do not like it. Create an account, if you have FB issues then make sure you use a Facebook account you don't care about, buy Eleven Table Tennis, play for an hour and then ask for money back for the game (can be done through the app) if you don't decide to buy a headset.
I don't know how the US is.
