Image no. 1 - completely badass!
Images 2 & 3 - Meh.
Everyone is talking about how awesome "the bat" is, but I think it looks kinda boring. One of the coolest aspects of a real bat are the scalloped wings, and when you are creating a plane for Batman, you really miss out on a golden design opportunity by not adding scalloped wings. You say; "well, the tumbler doesn't have any sort of bat-wing design".
And I say; "I've always thought that the tumbler was ugly too."
Luckily, Nolan is really good at making story & character driven films, or I just wouldn't be able to get past these designs.
