In my humble .44 magnum experience, the A-frame is clearly more accurate than the XTP in similar weights and velocities, but much more expensive and the theoretical terminal ballistics (i.e. in wet newsprint) are definitively comparable. I've never used an A-frame on game but have used XTPs many times - on deer-sized game, that is - and they have never failed me. Would not use an XTP on elk or moose though, as they have bones and joints that can be very tough.
