What meetup platforms are good?

I both go to and organize meetups. But even I have limited experience with all the platforms outside of the few I've tried. I want to check out others. But with so many it might be worth it to see which ones are actually good. There is like 40 of these platforms even among the ones I know about. So which ones are worth the time to check out?

I've included an optional poll since Lemmy doesn't have those. Maybe we can rank them.
