If you've got the bucks and want the best, get a couple of 6v AGM's.

AGMs ARE not "better" in ALL cases, period.
They are a "specialty" battery which unless you NEED ONE of the "special advantages" you are simply throwing out you money.
One of the supposed advantages is you can recharge at a higher rate which allows you to use a gen for less time. This HAS been proved to be a wash, basically put AGMs might shorten your charging time by a few minutes.
Another possible advantage is can be used in any position and do not outgass which could allow for placing them INSIDE your living space. I for one however do not feel that this is a wise thing to do since AGMs like any other "storage" system which CAN store a considerable amount of energy CAN be subject to abuse which can cause catastrophic failure.
The real advantage of AGMs is allowing you to part with more money, get less capacity for the same physical size as a flooded lead acid.
6V GCs ARE not "better" in ALL cases, period.
AGMs ABSOLUTELY DO recharge at a higher rate which allows you to use a gen for less time. Plus, AGMs DO charge cheaper due to lower resistance so that less fuel is used.
Another REAL advantage is AGMs can be used INSIDE your living space. In contrast, the 6V GCs will outgas and emit Hydrogen gas and acid mist in regular operation and that precludes any consideration of using them inside your living space or near any equipment.
