Since the 5.45 round is rare I'd go with the 7.62. And that said any problem you see with the 5.56 round or the M-16 family of weapons would be the same with that smaller 5.45 round.
I've never had a problem with the M-16 and later the M-4. I've carried them around the world in the Army and never had an issue or jam.
The best argument I've heard in the AK/M-16 debate:
The AK 47 is for a warrior, someone that will fight but has little training. The M-16 is for the disciplined soldier that controls his rate of fire and maintains his equipment.
