Eldar Wave Serpents win the vehicles
Tau Suits win for non-vehicles.
Yaknow, i used to think that too, but...the modest design of the hammerheads and pirahnas have grown on me since i've adopted this more mature paint scheme.
But, of course for the none vehicles they look frickin' amazing. I just hope they update the XV8's in the next codex to make them look a bit less doofy in the torso. Course the stealth suits are freakin gorgeous.

Tau have the coolest looking skimmers, with the Eldar a very close second. Chaos has the best walker vehicles since the Soul Grinder wins by several miles! For anime-mecha-looking-things, once again, it's really close between the Tau and the Eldar. I think the Eldar have a slight edge in sheer appearance, but the Tau are a little more anime because of their mobility. At the high end Eldar have it, hands down, with their Wraithlord Titan or whatever it is. Imperium and Chaos also get some nice Titan walkers, but the Tau have to make do with flyers that can kill them!
Agreed on the Skimmers. Chaos Soul Grinders are sweet but its difficult to respect the design because its gratuitously vicious. I love the Tau style because its modest.
Heres the thing though, I feel that its a bit unfair to call Tau and Eldar anime (i'm getting a little sick of people talking smack about Tau because they don't know what they are talking about). I gotta admit though that i love Mecha and sure the Tau have some similarities but I think people think the Tau are anime because they aren't WTFGRIMDARK enough compared to the other races. I don't know what kind of mecha they watch but theres a big difference between this...

and this.

Plus Tau are totally space communists which totally rocks.
Now, the Eldar Titan is cute and all but check out the Tau Titan. Sure its a custom design but I think this is EXTREMELY faithful to the tau design.
