Sc aquarium 100g is 48x20x24 vs 90g 48x18x24. What type of a difference does the 2” make? aside from the weight price is the same. The boss deep sixed the 90 cube she said we need something wider. Who am I to say no.

Water volume.
I would go with the 100. 2" will help in the stand for a sump.

^+1. And the little extra front to back will also offer more options for Aquascaping.
