I am now a fan of Deka GC15s 230AH, which have various brand names. They might be available locally at Costco or Sam's depending where you are. check the casing colour which stays the same whatever brand, and the specs for AH and weight, size, etc with Deka specs and see.
The Interstate 225 and 210AH batts are supplied by Trojan so they ought to be as good but might be a different "run" , don't know. it is possible the Costco Interstates are a different Trojan "run" from "regular" Interstate 6s too, don't know. Hard to tell with all the different case colours. Makes you wonder.
232 and 208AH are from when Interstate 6s came from US Battery, using their U-2xxx versions. EG a U-2200 was/is 232AH A 225AH Interstate is the same as a T-105 supposedly.
check this vs this:
