12v marine/deep cycle batteries

Like I said earlier, the marine batteries have performed well for me in the past once I had a decent charging system so I have no problem going that route again. I was just asking between the two I listed is one any better than another or is there something else in a 12v battery that isn't twice the price that you would recommend. I'm not debating 6v vs 12v or 2 batteries versus 4 etc. I see threads blasting Interstate quality and others on Everstarts, you also see those who have had good experiences with both. There is a guy here in Phoenix who sells Trojans and advertises like crazy so I will give him a call too.
