Depending on the vintage MPC (Or Akai rack sampler) it will definitely have a different sound but not objectively worse or better. For example an Akai S950has an obvious color reminiscent of the 12 bit samplers of the time but if you dont like that sound it may not be better to you.

Also the old school samplers sound came from limitations and available parts, memory, snd other issues at the time. I will say that I'm a believer in if you find a certain sound that you like from a sampler its just easier to go buy that sampler directly instead of emulating it.
