I'll have to say Necrophagist and Dream Theater. Too bad neither of these bands are good songwriters, though. For technicality AND songwriting ability, I'd say Blind Guardian and Death.

for technicality AND songwriting i would say Symphony X.
I don't know really, but I'm willing to say Gorguts if only for Obscura.
Arcturus, for most thought put into song
Also, Behemoth's pretty technical, at least Post-Satanica. Also, latter-day Death would be an obvious recommendation.
I'd like to throw in Beneath the Massacre, they may not be that great of a band,
Thought is nice, but that does not equal technicality. To be avant-garde is not to be technical, it is to transcend the bounds of general musical styles.
Some Arcturus songs are rather simple, but they are arranged in such a way that makes them avant-garde, regardless of how complex the instrumental parts are, as they contribute to a greater whole if the formula is right.
