Hmmm, I'm not familiar with those Guitars. I do have a Line 6 Spider III amp though that I love.
My dog ran into my Les Paul Supreme chasing a ball in the house and knocked it over and cracked the head stock. I went to the Gibson Store near me and found out it might take a couple of months to get it fixed. I wandered around the store looking for a cheap back up to fool around with while the other one was getting fixed and saw a Dark Fire on display. That was the first time I ever knew they existed. It was a complete impulse buy, but I absolutely love it.
Uhmmm, Yep it tunes automatically to any of about 2 dozen different tunings. Also, has a bunch of other bells and whistles. I find I don't use them much, yet. I just like playing it, I'm not much of a songwriter or composer so I don't use much of the other stuff aimed at computerized composition and recording.
EDIT--Not the one I was looking for, but a decent intro video nonetheless:
