Battery recommendations for TJ?

Sam's club sells the Energiser 34M AGM for under $130. If you are a member that's the way to go. O'Reilly has it for a bit more but still less than $200. For me it's good enough.
 
You probably don't need this info but the FSM recommends 500A and 600 amp batteries. Dont you live in the panhandle, you want the 600A for those harsh panhandle winters

I found a 720 amp Optima. I am new to trying to find something better than what I've been doing the past decade, just buying off of what I'm told is the new equivalent at Sam's or wherever. Is 720 too much, and is Optima still a good brand; I read something about them no longer being good, that they used to be good. What is your opinion?
 
Im a lead acid guy

All our DC batteries in our power facilities are lead acid
Easy to maintain, easy to add water & equalize

Ive killed waaaay too many AGMs over the years
Never had one last beyond 3-4 years

Ive had Lexus OEM lead acids last 11 & 14 years
Proper reconditioning (desulfate) cycles and recharges
However Im new to Jeeps so…..
