Just to elaborate a bit: if you look at the datasheets for the different FETs above you can see that the output capacitance varies a lot from large size fets to small size fets. If the output capacitance is too high, you loose control over the AGC shunting effect / series resistance effect since ther will be lower isolation due to the capacitance.
