Flooded cells will have the lowest price per watt hour and the longest life if in a temp controlled environment. However, they are classified as hazardous materials due to the amount of liquid electrolyte and that may affect zoning and insurance (if any one asks). I would not use a lead acid flooded cell unless it was in a temp controlled environment.
If you have 120 batts to replace, sounds like they might be outdoors. I would use AGM.

It’s that time… time to replace 90% of them, and looking for alternatives. Having to buy 120+ batteries… cost becomes something to at least look at. My local supplier says that FPL (Florida Power & Light – aka Florida Flicker and Flash) uses the Deka 7T31 non-AGM batteries (Lead Acid) and they are a lot cheaper (waiting on price – I found them quickly for $ 100 each). They are a 100ah batteries. Here is the spec otherwise http://www.eastpennmanufacturing.com/wp-content/uploads/Deka-Commercial-Batteries-Flyer-0010.pdf (minus the ah rating which I got from Deka over the phone). Does lead acid have distinct disadvantages from AGM? Also, anybody using Li-Ion yet for a tower battery bank? Probably not cost-effective ?
