They do? Seems like it's possible to design good amplifiers either
way.

Exactly - zero difference in quality capabilities. It's usually a
matter of impedance matching. Silicon transistors have a fixed loss
around 0.5 volts. MOSFETs have a resistive loss inversely proportional
to their voltage rating. That usually makes MOSFETs less expensive for
low impedances and transistors less expensive for high impedances.
