The SK punches hard for a 50w non-Wizard amp. But like Matt says...hard to compete with Wizard power sections. It's just something in the way they hit and move the speaker. Even the MC25s I've owned hit harder than most 50 and even 100w non-Wizard amps.
The GZ JMP 2203 MOAB+ I just got is one of the few amps I've owned that'll hit right there at Wizard level. Fucking amp sounds HUGE and hits so hard. This amp is on the same level as a Wizard in every category and actually seems capable of even more open/woody/organic tones than any Wizard I've owned. Insane dynamics and touch sensitivity. Like a Wizard, the clarity/articulation/definition is intimidating, but when your playing is on its something else. Can be wonderfully saturated with great compression in some of the switch and knob pull modes but it can also be one of the most raw/organic/room filling amps I think I've owned with gain cut pulled, lead gain mode off, and gain to taste. Need more time to burn the honeymoon but I'm feeling pretty confident this might be one of, if not the best amp I've owned. I've not had an amp leave my jaw on the floor like this one except for the first Wizard I owned, a 2017 MC2 100w E4L and a 79 loop modded MarkIIB. The GZ Hellion is a runner up and then the GZ Recto as well.
The Fryette CLX, D60, and The Splawn QR are a couple others that come to mind that I felt punched/hit close to those levels.
