Reaper has a well rather rabid following, and you will find Reaperites on almost every forum singing it's praises. I believe since the developers are out in the open and the users get to have almost daily input into the development. Plus the fact that the program is cheap, and has almost daily updates.

I have a license for version 4 and have used it, but i find i can do everything i need in RB.

Where Reaper really shines is in the area of routing of tracks. Every track acts like a buss, and or a instrument track, and you can send and receive to and from all of them in very unique ways.

Reaper is in my view still a long way off the top tier, but developing smoothly. It is a viable option, for those who do not want to spend the money on cubase, or sonar, and prefer daily, slow, steady development, over once or twice a year version based development.

I also own Sonar X1d, and it is a very solid program, while Reaper may be it's equal in audio Sonar is superior in midi. I find i like the work flow better in Sonar, partially due to familiarity, but also due to the fact that i don't want to have to go through the custom setup required in Reaper each time.

For me RB is like a simple, powerful, and comfortable old jacket. All my sonar plugins work in RB, SO i have a great suite of plugs to use along with PGs which are far better than most give them credit for.
