I have only heard the VTL and Wolcott. They are different in their presentation. The VTL is more traditional tube sound, but I don't mean too warm or slow. The VTL is excellent, better yet the Signature series 750 mono blocks.
The Wolcotts are almost as controlled as a big solid state amp, but with (only) tube personality. This is due to a patented design by Hank Wolcott. If you are fond of the control solid state provides for your speakers but want tubes, the Wolcott may be the best match.
For absolute "slam" factor and seemingly unlimited power, the big VTL would probably be the winner.
I don't know how you react to tube maintenance, but of the amps your considering, only the Wolcott is auto bias and digests every EL 34 made, making tube selections a delight.
If your using the balanced out from your BAT, the Wolcott has a convenience jack for balanced. This might save you converting the plugs. A minor thing, but a consideration.
