Things to consider is the stylus; whether it's elliptical, spherical etc.. Spherical stylii have for instance a tendency to leave dust in the groove because they don't reach the bottom (I think many scratch needles are spherical) but generally don't skip as easily and are more forgiving.
Another thing is the output.. we're talking in the range of 5-10mV max and that isn't much especially if the environment is very noisy (I mean RF noise, ripple voltages, internal power surges and spikes etc)
There are different cartridges when it comes to their operation like moving magnet (MM) and moving magnet coil (MMC).. I'm not experienced in that field other than that some RIAA/phono preamplifiers are specifically designed for different cartridges, but you most likely won't notice the difference unless in those very specialized applications and conditions.
