Sigh! The best is which have low enough noise figure not to ruin
the overall S/N, high enough gain to make your rig's needle to 
rise a little from zero and robust enough not to go into saturation
from nearby strong signals.

P-HEMT-amplifiers are amazing good.
Be aware those cheap "high gain" noise generators with over
0.5dB of noisefigure.
