The major advantages of AGMs over flooded are any position mounting, no watering and low self-discharge. You may read many other claimed advantages of AGMs but careful reading of the Trojan and Lifeline specifications show little differences in the capabilities of AGM and flooded batteries.
Lithium-iron-phosphate batteries (LFP) are in every way superior to all other batteries for RV use remembering they should not be charged when they are below freezing. This should not be a problem for most. LFP batteries do require a different charging profile (usually a new charger and BIM).

Will I need to change my charger/converter to charge LFP? Also, if I have LFP should I not leave it plugged in to my house if it’s below freezing?
