I have a Bose Soundlink Mini II, but heard great things on here about the Minirigs, so I got a couple. Ostensibly this for an installation I was working on, which didn’t end up going ahead, but my original intention was to find a replacement for the Bose anyway. Long story short, I’ve still got the Bose.
I like the form factor of the Minirigs, and the battery life is much better, but I think the Bose just sounds better. They both struggle a bit with resonant sounds with a lot of low freq content, but in the end I decided having two for stereo wasn’t enough of an improvement over the Bose. I also have a few things that use micro usb for charging, and nothing that uses the Minirig barrel-style plug, so having to carry an additional charger when travelling was another factor for me.
Just my $0.02.
