Deep cyle batterys

[bassin butch]

OK fellow bass enthusiasts heres a question for you:
What brand of deep cycle battery do you use? Have you experienced superior life out of a specific brand(s)?
I have used A/C delco, everstart, Exide, and stinger. My experience showed A/C Delco to be best with stinger coming in a close 2nd place. At bass pro shops I looked at battery isolators (Gel inserts placed under the battery) to reduce vibration which causes degradation to the batteries plates. Seems like a good idea but I think some strategically placed soft plastic baits would also do the trick?

The best life I ever had was 3 yrs of service, but admittedly I spend enormous time on the water so I feel 3 yrs is pretty good.
