Floooded cheapest, takes the most care and feeding and watering.
AGM most expensive, take very little care, can not water.
IF access for maintenance is not a problem, I'd go with Flooded wet cells.
Oh, personal experience report
Purchased motor home 2005, came with a pair of GC-2 (Interstate U-2200) Six volt flooded wet cell batteries.
Added a pair of Group 31 AGM (on a seperate properly set up circuit) in 2006,
Also added some Maintenance free's that pre-dated the motor home
Replaced AGM's in 2011
Repaced the Maintenance free's in 2012 (not really helpful since I do nto know how old they are)
Still using the U-2200's that came with the motor home.
2 days ago while I was cooking (With electricity) Dinner, I had the TV's and computers on and their support systems, the small electric (Aroma brand) Oven and the steamer (Proctor Silex) colking dinner along with the Air Conditioerns and a few other systems when CLICK the 50 amp park breaker tripped (Evidence of an issue with the park pedestal)
I can not tell you off hand how much power I was pulling through the inverter but when shore power was lost it switched in like any good UPS and took over.. Other than the Air conditioners and two lights in the bedroom that run on 120 nothing lost power.
I had to put my shoes on, go out and reset, They batteries held. The inverter held, The kitchen had to be drawing right close to 1600 watts.
