Every DAW will have a learning curve. None are fun to learn.
Just bite the bullet and do it. There are tons of tutorials on Youtube for Reaper.
No need to learn all the features on a DAW to work, still learning crap on Live and I’ve been using it for over 15 years.
^^^This.
I've had Cubase LE running on a laptop for, I dunno, 10 or 11 years now? It's my go-to DAW for capturing remote recordings, so it's the primary DAW for recording bands in their homes or rehearsal studios. But for those past 10 or 11 years all I've done with it once the tracks are in the can is take it back to my studio and dump the WAV files into a Macintosh running Digital Performer. Then any subsequent overdubbing, editing, or mixing gets done in that environment.
Well, I'm temporarily living 2,500 miles away from my studio now so I brought the laptop with Cubase to allow me to do audio work. Fired it up last night, loaded a multitrack session from a decade ago
...and spent 15 minutes trying to figure out why I couldn't hear anything on playback! Turns out in all the time I've used this DAW I'd never even listened back to what I recorded with it! "Yep, that was a keeper, next tune!" So now I get to finally crack the manual and learn all the Mixer routing and Insert functions that I've never needed to bother with, things that are usually part of any DAW's day one tutorial.
