the AUG is better. the previous answer was made by a man who
researched them but i have more experience with them. i am a
personal owner of both. although the Famas is newer and has more
modes of fire. the AUG is more accurate. the famas's accuracy
suffers at over 100 yards while a coffee cup is an easy target for
the AUG at the same range. the Famas also requires more maitenance
than the AUG. the Famas requires a replacement for the firing pin
every 20,000 shots. the AUG only requires a replacement for it
every 50,000 shots. it also has a higher rate of fire and maintains
long distance accuracy for every shot of its 60 round extended
Magazine. the AUG wins hands down
