The Diezel Schmidt would be my first choice over the others mentioned.

Independent clean, crunch, and lead channels, amazing reverb, series/parallel loops and loops for each channel, compensated out for direct recording that sounds exactly as the speakers sound, footswitch included, 30 watts, Class A that takes all types of different power tubes, and goes down to 15 watts with 6V6's, never needs biasing. 

Extremely organic feeling without too much sag.  Great EQ voicing that can do a whole lot of tones easily.

Takes foot toys extremely well.
