Changed?
1. Used Optima until 2008, when I got tired of their newer batts crapping out.
2. Switched to Sears Platiumun, last month I took one in for warranty, they no longer offered a 4 year AGM, so they replaced batt with another brand AGM 3 yr, and bought out remainder of the warranty with a store credit.
3. A Lot of my batteries sit for 4-6 months a year idle, and that seems to take a toll, not sure if they really worth the extar cost for top of the line agm's, other then bragging rights when it comes down to it. In vehicles used weekly, I have much better results.

Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.
