90g or 120g debate

[robzilla]

whats your thoughts?
currently have a 90g setup, it came with a store bought stand,
and i recently got a 120g setup with starphire front, homemade stand and lots of good equipment (tunzes/pm skimmer/neptune controller).
do i keep the 90 with the nice looking stand and equipment?
or do i transfer the contents to the 120g and redo the stand?
am i going to notice that much diffence in volume? the current tank is 18" across and the 120g is 24" across.

what would you do?
