I'm afraid I'll be of little help. I've scratched the surface of a few DAWs, but I don't know enough about any of them to give any useful input.
My only purpose for recording is to record my practice sessions so I can play them back and see where I need improvement (which is usually everywhere).
Since my needs are exclusively for guitar, and I don't play live or use mics, my needs are simple.
I attended a Roland/Boss product demo a month or so ago, and while there discovered the perfect practice/recording tool for me and my needs.
Boss eBand

Its clock radio sized, and has tons of COSM amp and guitar effects pre-programmed. You can also customize and create your own patches.
It has a USB and MicroSD slot for external storage, and has a USB cable that connects to your computer, where it becomes an Audio device, which can interface directly to your DAW or whatever.
The cool part for me is, you can upload your favorite songs in MP3 or WAV and play along with them. You can associate your favorite amp and guitar settings and save them. You can set up A/B loops within the song and set them to repeat so you can practice certain parts, and it has speed control and pitch shifting, so you can slow songs down to work out the harder bits.
And lastly, I can record my guitar either separately, or over the top of a backing track.
It's really changed the way I play and practice.
Anyway, this is probably not really what yo are looking for, but I thought I'd mention it in case anyone is interested.
