Metagross punches some HUGE holes in unprepared teams and is still a nice SR setter. Chansey is an excellent wall that really doesn't give a shit about anything but STAB Fighting moves. Overall, though, both are on the wane, as better and/or more specialized Pokemon are gaining popularity (Rotom-H, Gastrodon, Deoxys-D, etc).
I think Chansey is better.
