The Quest 2 is definitely worth buying. It is great for VRFitness. I tested it with the Reaction unit. Reaction could not really be used for training with the Quest 1, because it is our most computationally intensive unit. But with the Quest 2 (with 90hz) no problem and it really makes fun. The Oculus browser supports 90hz, I tested it. And the face covers and smooth grips from the Quest 1 also fit.
