I mean, it is super powerful, and it does things that I can't (currently, or easily) do without it. But I wasn't really using any of those features anyways.
I would have never even looked at the regular CataRT stuff since it requires ftm and that's waaay too big a dependency to casually take on. I only looked at mubu as you could do similar things with just a handful of externals, but the help files aren't great, the support forum isn't great, etc... And in the small amount of time I used it a minor update broke stuff that took me a bit to track down. Did not bode well for long-term development.
