Pick the one with the highest output current, and the best specs into a low impedance or possibly reactive load.

 

Why no β22?

yep, so is the o22 pretty much, but would you use one in a cmoy? i'm assuming hes meaning portable, semi-portable, or at least semi-budget. just doesnt seem to tick any of the boxes to me
