I have the Bose.
I normally hate Bose stuff and I thought the Bose Soundlink II was pretty pants, but when the mini is given a bit of EQ (up the mid-range/top a bit) it sounds pretty decent.
It conveys a lot of bass – think of it as sounding like a small club soundsystem rather than a hifi system.
It has a particularly tuneful, head-nod inducing, bass.
I use it as my speakers on the PC when not traveling and I use EqualizerEPO as an eq :

with this GUI as a controller :

and something similar on the tablet/phone when using bluetooth.
