I took a chance and just recently bought 2 of the 235ah. The reviews are good, we'll see. I don't know what the warranty is on other brands, but these are only 12 months.
I cannot say how they compare to T105's, but they have solved my issues. We dry camp 3-5 days and are often constrained on generator run times. The old marine battery didn't cut it. I was going to spring for a solar setup. My two SLIGC115 batteries have me rethinking the necessity for that.
The bad news is; I have only had them for a few months and a couple of trips. It takes a while to figure out a battery's worth in the long term. But in the short term, they have made me happy.
