If you do a lot of camping off the grid (boondocking, dry camping) it's hard to NOT recommend Lithium. Twice the available power in one quarter the space and half the weight. Added benefit of being able to install the batteries inside both away from thieves and weather.
Often good things cost more but often don't need to be replaces anywhere near as often as the less expensive option.
If still looking at a pair of 6 V golf cart batteries I'd go with Sams, Costco, or Interstate as warranty service will be pretty much available anywhere. In most cases the batteries are made by either Johnson Controls or East Penn. Brand names are applied for the companies that market the batteries and don't manufacture anything themselves.
