I've been using Reaper since around version 3.x and for the money it's hard to beat. It is a bit clunky to move around in though. I'm not really fond of some of their midi editing tactics, but I can get things done with it. I guess the thing with it is you really need to dig into the manual and tweak the UI/menus to your liking. I also use Live but haven't used the composition view much...I need to look into it more. The one thing that bothers me is it not having a built in 32bit bridge like Reaper. Not a big issue as I can run it and Reaper at the same time...I use Live as a midi source and pipe it into Reaper. I do this on a relatively newer rack mount PC that I built. My laptop got to be underpowered and instead of forking out a bunch of money for another one I just went the normal PC route...I can get more mileage that way for less money. I used to use Saw Studio...still do for some editing but it's handling of VST(I) is weak compared to the other two. Sounds great though.
