Santa Fe and it's gem of an engine, for me.

The Fortuner, Everest and Montero Sport do look big on the outside, but they have similar tight interior room. By comparison, the Innova is about as big inside as they are. You do, however, get a higher ground clearance for those time when you do tread the unpaved path, but then dirt roads that the 2.5L 4x2 can handle aren't much worse than what the Santa Fe can do.
