All depends on how much money you want to invest. I opted not to go with AGM because of the up front cost and chances of a failure of one battery which usually results in replacing all too start over.
The Trojan T105's are about $50.00/battery cheaper and will do most everything you want for a house battery bank. Depending on use/abuse, changing them every 5 years does not break my budget.
Trojan T-105 6V, 225AH (20HR) Flooded Lead Acid Battery
My other consideration was that I have three battery banks that are charged by all systems, and an AGM bank would not work with my setup.

The cost is only $80.00 difference, anyone have an experience with the four AGM 6volt batteries?
