Since you have both Reaper and Real Band, play with them both to see which one you prefer to work with.

Try using the same function in both, then try another function, try audio editing, envelopes, bouncing, recording, and as many other functions as you need to do what you wish to accomplish.

This will tell you in short order which one is easier for you to work with. I could tell you why I like the DAW I use but I won't. It's not one of the ones you have. Before you spend money on anything, work with the 2 you have now and see if they are suitable for your workflow.

Add nothing that adds nothing to the music.
You can make excuses or you can make progress but not both.

The magic you are looking for is in the work you are avoiding.
