This was a tough one, actually. While LTE didn't release any new material, per se, they released a KICK-ASS live documentation of the short reunion tour - two whole live shows on CD and DVD (NYC and in the case of LA, also Blu-Ray), half of Chicago's show on CD, and a bonus disc with improvisations from the other shows.
Granted, TA came back together with an AWESOME new album, in three different release variations (standard single CD, 2-CD, and 2-CD/DVD sets), and have begun a (comparatively) lengthy tour of NA and EU. However, from this reunion/tour, MP's released his obligatory drumming DVD - Whirlwind Drumming - and Neal's buddies have put together the TA Official Bootleg DVD (which is FANTASTIC, by the way, and everyone should get a hold of one somehow)... so we're still getting more out of TA, and of course, there's the eventual live release (which I expect to be at least a 2-DVD adventure, and 3-CDs... perhaps a 5-disc set like DT's Chaos In Motion).
So after all that in consideration, TA won out. Now, if LTE came back and did another album this year before TA releases their new live album, you might want to post this poll again... LOL
