For starters, try to do everything you can do on the bench with 
a real circuit.  setting the bias, distortion measurement, 
tweaking it in, comparing AC response of top half to bottom 
half, effect of component variation, adjusting frequency 
compensation for best stability, adjusting thermal compensation 
for best thermal stability, ...

Then imagine all the stuff you would like to do but can't do 
with a real circuit. ..  looking at internal signals, which you 
can't on a real circuit because the probe changes it, looking 
at parameters like transconductance, with signal, ....

Simulation should give you lots more  information than you can 
get from a real circuit.
