The Model 60 will be a bit stronger but the 37 is lighter for CCW.

I carry a Model 37 and gave the GF my Model 60 as a nightstand gun.

As for value if they are the same generation.... I would get the one in better condition ,
If the Model 60 is pre 1969 gun I would buy that one.
If the Model 37 is a flat latch buy the 37
