We camp on both electric sites and drycamping sites. However, I hate equipment surprises .... especially out in the middle of nowhere when boondocking.
Quick charging, deep discharges if ever necessary and ultimately, reliability, are the name of the game when you need to be ready for anything or any type of campsite. I also don't like RV equipment surprises at home just before embarking on a trip. I want stuff to work and in the case of RV batteries, I don't want surprise acid fume damage or low cell water levels.
We will use AGM RV batteries until either lithium batteries or automatic fuel cell systems come down in price. ;)
