Movie Leader Brawl is awesome and my favorite. After him, RotF Bludgeon/Banzai-Tron, Armada Megs/Galvatron/Botcon Megazarak, and Cybertron Defense Scattershot are also pretty badass. I'm eagerly anticipating PCC Heavy Tread and Classics Warpath.
for me their are 2 ways you can pull off a tank alt mode. 1 just a mess of metal and guns or 2 a very close to like approximation of the real deal for the best pile of guns I'd have to say G1 Hardhead and the the best realistic looking alt mode I've have to say Banzitron its perfectly proportioned and it looks rather tame compared to other tanks but that totally goes out the window for the robot mode. On a side note I really don't like many H style tanks it just kinda seems silly to me
didn't you hear, straxus doesn't count. pffft....some people just don't know the difference between a self propelled gun and a tank.
Until they give us a CHUG version, G1 Blitzwing. In the unlikely event they screw up his tank mode, then ROTF Bludgeon.
I always liked Quake as the best tank mode. I liked his bot mode too, easily one of my favorite decepticons.
My favorite tank transformer is Animated Shockwave, but not for the tank mode. That would have to go to TFTM Leader Brawl.
CHUG Brawl from Bruticus Maximus. 1. Brawl is a combiner part 2. Brawl is suitable for army building (if only we can buy more) 3. 4 Brawls with 1 onslaught can form Bruticus 4. Brawl is fansproject friendly conclusion = win.
