I think people are overlooking another aspect here.
Different programs have different functionality and workflow. While Dubstep can be done in Reason, another program may give him a better feel and more ease for his exact methods of creating music.
Example...I love reason to death...but but when I sample in Reason, I have to...
1. Load the track into Pro Tools to chop, timestretch and pitch shift, then export/bounce down.
2. Load the .wav/aif into NNXT multiple times to be effected different ways and set different start points.
Not hard at all, but others will come up with 50 other ways to do the same task including use of Recycle, Rewiring and leaving the sample playing inside a DAW, using the timestretch and audio editing functions in an Audio Clip inside Reason. Use prior step, export and reimport into the NNXT since I like it so much. None of these ways are "better than mine' for me.
That concept can pass on to use of another Program making things easier...because in FL, I just edit in Edison and time strch/pitch shift in my audioclip. Never have to rely on another software for anything whatsoever. Again, others may edit before loading into FL. Use FL Slicer instead of Audio Clips, ect. ect. ect.
Ultimately I'm saying, even though I enjoy both, and can get the same results doing both, sampling on FL is waaaaayyyyyyy easier for me. If I never used FL before Reason, I would've overlooked the importance of timestretched samples in developing my ways of doing things and would've excluded this key factor in my sound out of lack of knowledge it existed.
It can go vice versa as well. Reason(Redrum) has taught me alot about drum tweaking that I've taken back to FL. It's also taught me you can get good realistic basslines out of a good sampler patch. I never woulda learned that in Boobass and 3xosc.
But hear me out, Maybe, just maybe(and I'm not trying to challenge prior statements because I agree the tools don't make the producer) if the OP switched software, he'd find functionality and workflow that he's feeling he's missing right now.
I mean, that's the reason i switch software, speakers, move around my room, bring out/put up gear ect. every few months. A new environment can spawn new creativity. In that case, I'd agree it's time for the OP to move away from Reason to something else, so he can learn new approaches that will come in handy when he get's bored with his new choice and returns to Reason in a new perspective. Could be in a few months, maybe a year, maybe even never if he falls in love with his new approach, but nothing wrong with options.
