Sam's Club sells Duracell which are actually manufactured by East Penn. East Penn manufactures for several other brands including Deka.
Trojan or Rolls Surrette are the best, but as mentioned by Trackrig, I am not sure they are worth the premium price. Gold carts store typically carry Trojan. Industrial supply houses carry either Trojan or Rolls, but they may not stock the GC2 size. Solar power stires also, but again, they probably don't stock GC2.
I think the Deka or Duracell is the best bang for the buck. They have a 235ah 6v for $150.00 ish bucks. I have 4 of them. Had them since 2018. Working great.
