Why not just go the four hours if he is the best?
While I know nothing about either of these doctors and I'm sure they both will do fine, being a diplomate of the ACVS would be extremely important to me, otherwise they can't really say that they specialize in veterinary surgery...
Another thing you might want to take into consideration is pain management post op. A Yorkie had surgery at Michigan State University for LP and was only given a couple days of pain meds. They didn't want her feeling too good to early evidently. However, I do not agree with that at all... This person ended up getting more meds from their regular vet but I know you aren't happy with your vet(s) right now, so maybe you won't be able to depend on that... Then there is the issue of will she be hospitalized without supervision and the anesthesia that is used.
