Nice kit Morgz and how good to be aboe to run a comparison!
I agree that the VBM is a terrific machine. Loved it when I first used the 2B V1 at Aromafest and still like it. There is some very clever thing in the layout.
Agreed on finish- the Duetto currently has it. Both have big, big steam and yes- the VBM probably has the edge. Ultimately, both have more than you'd need- but I'd like to see a redesign of the VBM wand and tip. This is really just nit picking though.
Ultimately, the proof is in the cup and you have 2 lots of proof that both are fantastic combos which is exactly what you'd expect this high in the price range.
