To give you a real unbiased answer as someone who's actually used the headset, the Quest 3 is the best VR headset you'll get for the money. Pancake lenses are amazing, performance is really good, software has gotten ages better since launch. Meta throttles the chipset a lot, with QGO (an app) you can meet or be just under PC quality on most games, but the base headset is fine by itself.
As for games, there's never been a better time to hope in. But I'll be honest my Q3 is practically a beat saber machine at this point. I haven't found another game to be as enticing. Pistol whip was meh, I couldn't get into B&S or Asgards wrath, Metro Awaking isn't my type of game. It's really up to you to decide how valuable VR is.
Sonic Unleashed was my game. Second only to Sonic Black Knight.
