I am sure I am the oddball here but I am running 3 yellow tops and 1 red top Optima, I have a diehard platinum in my Viper. IMO the key is a battery tender device, for an optima I believe CTEK is the best by far (I have quite a few different ones and the CTEK is the only one that brought back a drained yellow top recently).
I have one battery that I have had for 10 years, another for 6, etc. There are some really good batteries out there now, for me it is about the convenience of being able to go locally and picking one up.
