Had to vote standard.
I have a 90g standard and a 90g bowfront.
I really like the way the bowfront looks (and yes there is some visual distortion at angles, especially really close to the glass).
They are WAY taller then a standard.. even at 6'1" it's a stretch to reach the bottom of the tank on the oceanic stand (all glass oceanic...whatever....)
It is more difficult to clean - heighth lends to stretching, those magfloat scrapper dealies don't get good magnetic attraction.
Placement of items gets a bit odd too... what looks about right from above may appear way too close to the glass and vice versa. Normal for water I know, but especially more apparent in a bow front.
Anyhow... gl with the purchase.. I know a 175g bow would look awesome...just be sure to get one of those ladder/scaffolding systems to work on it
