I highly recommend Briggs & Riley. I have two rollaboards, basically one with the garment bag and one without. They'll give you the interior room you want, although the garment carrier takes up a significant amount of space.
Whether you get the expandable one is up to you.
The best thing about B&R besides the high quality is the lifetime unconditional guarantee covering everything, including airline-caused damage.
When you shop ebags keep in mind they partner with several FF programs, so shop via your airline website and get miles too.
