They also both have the ability to show max. temp attained on the esc and a full current "launch mode"--hold down the brake for 5 seconds before start of race. Unless I am missing something I don't see a difference.
I heard that the TC Spec has better brakes than the 2007 Sphere Comp, but I can't confirm that because I don't have a TC Spec. The major difference between the two speedos is that the heatsink on the TC Spec is mounted directly to the FET's, which means there's less of a chance that the blue smoke will escape.
I'd try one out, but I'm happy with my 2006 & 2007 Comps.
