Today though? I still use OBS even though I still have XSPlit (I got a perpetual license). If there's something much better that isn't thousands of dollars, I'd like to know what it is.

There's a lot of commercial editors that are nicer than Gimp, and Office IMO still beats Libreoffice and isn't that expensive. But OBS? I don't know anything much better.

The plugin ecosystem and the community support is just top notch too, because EVERYONE uses OBS. If you use a commercial option, it's much harder to google up how to do some stuff.
