Not quite all, but I've had the moab, the mgl 50 red, and a lenz octane.
The Moab is the most versatile--every option you could ever want is in there. Jeremy is also super fast and communicative. I'd take the moab.
With that said the MGL 50 red was excellent. Sounded big, not as customizable but had a great sound and play feel. The moab felt more "traditional hot rodded marshall" and the mgl was a little darker low-mid emphasized and sounded slightly more modern.
