I bought a G1 Compact pretty much as son as they came out. Before that I used enormous Trace Elliot cabs that sounded nice but were too much for my poor old back. The Compact was no only light but sounded immense - perhaps lacking a bit of top end clarity. I added a G1 Midget, which by itself lacked bottom end, but together with the Compact made what I considered to be the perfect rig - the two cabs complimenting each other perfectly in that it was full spectrum, lightweight and a pretty transparent output. I didn't see myself changing, tbh.
Then Alex brought out the Supercompact which was claimed to sound exactly like a combination of the Compact and Midget - the perfect one cab solution!. I bought one and was blown away with just exactly how full range, lightweight, transparent, loud, small to load in and out etc. it is For my particular requirements the Supercompact represents such a perfect one cab solution that I, er, bought a second one.
Simply because this one cab does what two cabs did before in a smaller single unit and with a touch more transparency I would say the Supercompact is a better cab to aim for - if the sound is what you are looking for. Some people prefer the more coloured sound of the Retro range.
I have a One10 for its extreme portability but haven't tried any of the rest of the range to compare.
