Payware PSS A320 series. Questions

I have the A320 payware series from PSS (A319, A320, A321).
I like them all but I can't quite decide what's the difference between them.
They all look the same, and aside from a different weight and power they feel the same.
Do you guys fly any of these? What do you think of them?
Do you have a favorite?
