You would probably be happy with either. I have enjoyed an MC452 for several years, originally pairing it with a C50 solid state pre-amp, changing that to a C2500 tube pre, enjoying the slight difference in "musicality" the tube pre offers.
My only opinion about going with a C402 is to consider that it's X number of years older and will likely need to have those parts that wear over time (like capacitors) replaced sooner.
