I think i have more questions than answers. How much are you looking to spend? Any particular "must have features" (laptop access/ water proof, buisness looking etc.)? Have you ever considered cutting the wheels and going back pack? Frankly i don't think much looks good at all in the roller luggage class.
A few interesting choices are the ever present Tumi, B&R but you also have some interesting "tactical" bags on amazon with rollers now and two pretty interesting upstarts. The G-ro has those giant wheels which can get you over curbs and sidewalks without what i call the "scuff drag" maneuver (I think you could roll a G-Ro up a flight of steps if you really had to without lifting it

Also nomatic just launched some interesting travel bags on kick starter.

Another option would be a "continental" line of bags made in the US which are a larger and more expandable than the "international carry on sizes" such as this:

You'll notice with that Tumi Continental expandable it can be unzipped and expanded in dept from 9 inches to 11 inches so even though it still has the same 22 inch height you gain an extra 11.5 liters via the expansion zipper.
