Both are very good. Best choice now is the a57 due to price drop. Very good evf and IQ. a65 evf seem is slightly better but I tried few time demo both camera in concluding a77 last Sat, the difference is not obvious to me. But some people see it is huge differences. So better to try both yourself. What I think is, if you need 24mp should skip a65 go to a77 which is a better camera to give the higher mp justice.
