I have demoed REAPER many times and tried so so hard to like it. The app is very well priced and has a decent feature-set, but I feel that it is very poorly designed. This probably comes down to the fact that they add a heap of tiny features with extremely quick, un-planned updates.
REAPER now is a pretty big mess when it comes to menus, preferences, general workflow and usability, at least that's how I feel about it. In addition, it lacks good MIDI editing, elastic audio and a few other very important features.
Studio One is a breath of fresh air, and pretty much works just like Cubase in many aspects. Though, it's still a pretty new program and lacks things like Elastic Audio, which are really REALLY useful for music production. I think that this DAW could be a true contender in the near future.
I'm curious to hear your thoughts on these 2 DAWs.
I still personally believe that the biggest contenders are Cubase, Logic and possibly Live
