I do own a Baby Sumo and it's a sweet little amp. I really dig the simplicity of having just an on/off switch and a master vol. IMO the size is just right. It is heavy enough to sit tight on a cab even when there is a a bit of tension on one of the cables.
But I don't use it as much as I thought I would. I take my Tonehammer on lots of occasions and plug into the FX return.
The Tonehammer has two features that make it a bit more useful to me:
1. Two speakon outputs. Sounds trivial, but I often rehearse in a place where the cabs I need to use are set up for the guy who owns them and plays them with a non bridged poweramp, so there are two speakon cables to plug in or re-routing the cables which is a PITA because the cabs are semi built in to the room and their backs are hard to access.
2. Another DI out. This comes in handy when a) I need to send 1 signal to FOH and one to IEM or
B) when I have pedals after my preamp/DI and only one wet signal that comes out of the last pedal.
