As you say, different strokes.
I have a quite specific need: I'll be gigging (for example) tomorrow night in a pub and then Sunday afternoon at a rock'n'roll club. After each gig, I want to take the audio and tidy it up (not drop-ins and such, just a bit of compression and EQ), then match that slightly-enhanced audio to the video taken at the same time. Then I can pick one or two of the best performances or the songs with the best dancing or the ones which make me look even better than I really am and produce a couple of 3-min videos for publication that very day.
Being able to do all that, really quickly and easily, and all within the same product and interface, is an attractive proposition.
If I was setting out to re-record Dark Side Of The Moon then no, I probably wouldn't recommend Reaper. And if I was looking to re-edit Life On Earth then no, I probably wouldn't recommend Reaper.
It's horses for courses, innit?
