During the pandemic, VRChat let me reconnect with friends that I hadn't seen in person for 1-2 years. Combined with body tracking modules (so you can walk around fluidly), the experience can be extremely immersive, like you're in the same room with someone.
When I upgraded to a Valve Index and gave my older headset to my roommate, he later mentioned that VRChat and the social experiences he had on there saved him from a deep depression brought on by isolation during the pandemic.
I'd consider that an extremely positive experience.
