I have never designed or made a Mosfets amplifier because of the wide range of Vgs requiring matching or adjustment.

MOSFET amplifiers not requiring adjustment.
I have built several of the second design and they do bias up properly every time, and track with temperature.
I have only built one of the first design and it did bias up properly, so my confidence level in that design isn't quite as high.
It does require some matching of MOSFETs, but "from the same batch" was close enough.
