I'll never understand why people are so "fire up" about AGM batteries. Unless the battery is mounted somewhere that it might tip over or in such a terrible location that serving a flooded cell battery is nearly impossible, it just does nor seem like it is worth ANY extra cost.
Here are my likes of AGM, lower parasitic loss, can tolerate deep cycling, much faster recharge time, and twice the service life. I'll fess up, this is what I'm told and don't have a long experience with them. My 2015 RAM Cummins came with a set of AGM batteries. Time will tell if my loyalty is misguided.
Yes, there are some "good" points like you have mentioned, the problem is the bad points that folks gloss over, like..
LESS Ahr for the same PHYSICAL SIZE (IE takes MORE AGM batteries to equal Flooded Lead Acid).
DIFFERENT charging voltage profiles than Flooded Lead Acid..
Overcharging to the point of the VENTING WILL RESULT IN A EXPENSIVE DOOR STOP!
MUCH HIGHER COST PER Ahr!
If you are OK with spending more to get less Ahr capacity go ahead and do it.. Personally I am not OK with spending more to get less capacity..
Carry on.
