You got a good deal. I'm happy with my Scarlett 18i8. It's a fine USB interface.
I particularly like the MixControl, because you can create your own submixes for different outputs (e.g. two different headphone mixes and one for monitors). It is controlled in the software, but it happens in the interface for zero latency monitoring during tracking.
I use Reaper so I did not install Ableton Live Lite. The effects plugins (VSTs) are ok, and if you find a sound you like, the BassStation VSTi is fine. I don't use the Loopmaster stuff.
I use it in two different "modes". For one, it is my practice rig, basically a mixer for my instrument, with whatever other inputs I might want to play with. This could be a DVD, CD, drum machine, or a track that I created in Reaper using VSTI's. The other mode is for recording tracks to the DAW. It performs very well in each of these modes.
FWIW, the number of inputs I have is overkill, but since I use it as a mixer, it does save me from having to swap cables as often. If I could have gotten the deal you got on the 6i6, that's a better value for most people.
