Anyone else using Reaper?

I use Reaper. I probably don't use as many of its features as would be useful for me if it was more obvious how to do them, and sometimes I export to Ableton for certain tasks, and it's sometimes a problem that I don't use Logic (collaborating with other musicians and they have to send me stems instead of a whole project). I was originally going to say that Reaper does the job just fine for me, but having typed out these three points I'm now thinking I might just be stuck in my ways lol!
