I've thought of this question a lot,
Tall tanks seem to be better for coral IMO. The height of the tank allows for more rockwork and various levels of depth for different corals. As others have said, I find cleaning to be a bit more work and lighting can be a bit trickier for an odd sized tank like a 45 tall.
I love shallow long tanks tho, one of my favorite tanks is the 40 gal breeder. Clams look great in a tank like that.
Also, certain animals would like tall vs long or vice versa, such as sea horse who generally need a taller tank to breed properly.
I think the real answer is...get the biggest tank you can!
