Start by reading this:
I've always used the ARR GaAsFET pre-amps never had a problem AND have
noticed increased receiver performance. However, often times you have to put
a pass cavity ahead of the pre-amp.

Only one part of the equation. If receiver B has
better front end protection/preformance, it's
going to be a better choice.
Many of the newer commercial and older low dollar
repeater receivers crap-out on busy mountain tops
and repeater sites, especially when you park a
gasfet mixer (preamp)

0.35uV is the rated sensitivity of most Mastr II

the preamp (info from the manual).

Chip makes repeater receivers?
