That you've tried. The "big boys", aka Cubase, Logic and ProTools are not getting mentioned as contestants whenever people declare Reaper to be the king, and I can only assume that was because they weren't ever tried in any depthhibidy wrote: Reap is best, by far, not even close. Did I mention how much better it is?
Ableton was always a weird niche kind of DAW that never favored MIDI or instruments, Fruity Loops was always just this weird thing marketed towards "beginners" just like Reason, and the newer stuff is likely not matured yet, just like the early days of Reaper found it a bit lacking in many ways...
But FFS, let's not declare Reaper superior to the "big boys" without actually trying them... and I personally despise Cubase, Logic and ProTools(nor have I personally tried their most recent versions), but fair is fair...
