Voted TDKR. It's fun to see the cave go on for miles, like that fold out they do in the All-Star Batman & Robin, with various cars, tables of gadgets, big room of bat costumes, trophies and what not. At the end of the day I think it should be as minimalistic as possible. Batman hasn't the time to actually "decorate" his cave, I'm sorry.
I do enjoy the parking space for the Batmobile, the vault and that space of monitors in Burton's first film.
But Nolan gave me that nice waterfall, with the single computer station and the batsuit rising in that case from the water. He took the minimalistic point of '89 and I think stylized it a bit. Hell, Begins was great with this old elevator that took him down to a small narrow with like an actual chest holding the cowl.
