Interface: Cartridge-Preamp or Cart-Tonearm?

I'm trying to choose a cartridge.

Which plays the more influential role, the cartridge / pre+phono amp interface (electronic complementarity) or cartridge / tonearm interaction (physics of tonearm-cartridge mating), all other factors being equal? assuming correct setup with proper cartridge-arm load matching...

Or, as in so much else in audio, does each contribute differently --and if so, how do the two differ, as relates to choosing a cartridge?

If need be, I can specify the equipment involved in my choice, but this is intended to be a non-specific question --at least at this phase of inquiry.

Thanks in advance for sharing your experience(s).
