I have been running AGMs in all of my vehicles, the biggest thing I have found is if you slowly run them dead (sitting not on a maintainer,) they don't seem to come back very easy.
Thoughts on Optima batteries?

Some do, Optimas especially don't. That's why Optima was forced to introduce their own special charger to help recover them. A standard battery charger won't bring back an Optima that has too low of a charge.

A deeply discharged Optima won’t charge with a standard charger because they will discharge below 10.5 volts , which a standard charger recognizes as a faulty battery. You can connect a charged battery in parallel with jumper cables (pos to pos and neg to neg) and then connect a standard charger to the good battery to revive it enough to connect it by itself. Make sure you disconnect your battery from the vehicle first.
