I took a 6 of my friends to this concert, all of which have heard at most 2 albums (a few times each, MAYBE), and at the lower end, a few songs. All of them thought that Dev put on the best show of the night. His showmanship, his enthusiasm, his fucking voice... it was fantastic.
Scale the Summit and BTBAM put on solid enough shows. The crowd was really going for BTBAM, but they were the headliners after all. Cynic was... okay. I like them, but they really aren't a good live band. Their show was pretty boring.
Really, my only quibble was the choice to play By Your Command. It's a fantastic song, but the last 4 minutes are Dev playing arpeggios with overdubs in the background. If he wanted to go the Ziltoid route, maybe Color your World would have worked better, seeing as how that song would be lacking in overdubs.
Regardless, I can't wait to see Dev headlining a tour next year. I've only recently became a fan, not long after Ziltoid came out, and when I originally heard he never wanted to tour again, I was disappointed. But now that I've seen him, and he seems rejuvenated, I can't wait for the next few years of musical output.
