There is no need to argue about what's better or more useful. Imho, it depends on a personality. For one weightlifting is the best exercise, for another it's yoga. I think we don't get obsessed with specific movements, we get obsessed with things we do well. I'm new to yoga. I just started practicing it with https://yanvayoga.com. It's hard for me at the moment, but I like asanas that I already learned. And I can definitely say I couldn't be obsessed with weightlifting, because I don't like it.
