My surly is 4130 and I'm very happy with it. Although it does suffer the same coke can sized head tube skinny steel fork aesthetic discussed here earlier. Easily solved with a carbon fork upgrade later on maybe. But I've growth to quite like it as is.
I do agree with @amey that best performance for the £££ will come from Giant, Trek, Specialized etc but given the choice I'd buy the surly again as I just love riding it.
