You may as well ask are the attackers insecure in their choice (i.e. does Reason give them the willies, and they're unable to switch to it solely because of dependency on plugins and MIDI out), why do they care so much that they attack Reason so often, why do they stress an irrelevant "icing on the cake" level of phatness that's going to get eq'd or mixed out anyway over incredibly important issues such as productivity, flexibility and stability (some of Reason's very strong points IMO), and why (almost culturally) FL Studio users are usually the attackers.Are you insecure in your choice? If you love your program and work well with it, why do you care so much? Why do you always attack everyone saying they have sub-par production skills? And why are you especially aggitated when FL Studio is mentioned?
As for sub-par production skills, Reason does take more production knowledge to get to grips with than your average plugin host. Some folks think they know what Reason's capable of by loading up some presets in the Subtractor and calling it a day...I mean seriously - dull? thin? If you can't easily make Reason sound far too bright or phat for practical use, your studio skills probably are sub-par.
Someone's got an inferiority complex or needs to prove something to themselves and everyone else, and I doubt it's primarily the Reason users because the attacks outweigh the defences. It simply draws a conspicuous amount of contrived, agenda-riddled flack, way out in "the lady doth protest too much" vein.
Reason isn't even my main host anymore, but the amount of just out-and-out bollocks (you can tell because often there's no consistency to the attacks) posted about it online is unbelievable.
