This was back when I used a stock Classic Army AUG in 2010, so perhaps lipo-ready AEG's don't have this issue. I know that MOSFETs do fix most of these issues.
Honestly, at these low voltages and current there isn't much to tell between the performance (when fully charged). Keep in mind that current isn't really "pushed", it's "pulled" by the motor. The biggest draw to lipos is that they have a much flatter discharge curve and for the same capacity they are much lighter. So for a given weight and size the lipo will perform longer and more consistently.
