Surprisingly i think this is an easy choice.
Not only do the QSx outperform the direct speaker style for surround usage (at least in ease of placement, not quality of sound), but they are also much smaller than one would expect them to be.

Unless your daughter wants to take the time to setup a proper surround area or specifically wants 2 full sets of direct speakers, i would say the QSx would do the job admirably and compactly with its small size.
Besides that, they have an atypical aesthetic factor to wow her new college friends.
