I have been buying red top Optima's for everything that needs a new battery, thing I love most is the lack of corrosion at the terminals, a real problem with some things I have used them in.

Time will tell if the economics of the more expensive battery is worth it, but I have had much less maintence that was very time consuming and annoying since converting to them. 

I have been told local stock car drivers and demolition derby cars have been using them because they won't explode and/or leak in an accident, don't know how true that is.
