We have run both and recommend AGM. A decent automatic charge relay or battery link from Blue Sea Systems is all one needs to connect the vehicle AGM bank to the house AGM bank. If solar is also present either device will automatically separate and join the banks for starting and when either side reaches high enough voltage to dual charge. We much preferred the set it and forget aspect of having an all AGM set-up and that both of our banks were always fully charged from either driving or solar. The advantage of a battery link over the automatic charge relay is that it also has a built in battery charger, it's compatible with both 110 and 220 sources so it's perfect for world travel.
