I feel it would be more fair to compare hellrazor and hellion. The mtl2 is a solid amp. But the other two are fucking beasts.
However, this is a time when you would want to play them to see what voicing you like. They all will have punch. The hellion is much tighter than the mtl2 and tighter than hellrazor. The hellrazor is like a mtl on steroids. It is one of the best amps i have come accross. Maybe the best.
I would like to spend more time with the hellion. It is a very special amp also. But i feel like it has so much versatility. And i think the hellrazor is going to be more specific.
The mtl2 is a fun amp, more low mid than some of the wizard offerings, but still that wizard high end. It will do everything you need and have punch for days, but you will want a boost with it for certain stuff.
