I had the same conundrum when i got my 210. The height makes it look a lot better, and the added water volume is a plus, I have south americans and a couple rays in mine and to be honest, some fish really do occupy all levels of the tank.
because of this I actually bought a 110 yesterday to upgrade my 75 for the same reasons.
