6v or 12v?
All else being equal, which is preferable and why? 2 220 AH 6v batteries or 2 110 AH 12v batteries

People are in favor of 6V for less cost for same capacity/durability. Disadvantage is that you need both batteries to power your system.
I have no reason to switch to 6V batteries currently since either system works for my purposes.
It's true but a decent battery that is maintained with proper monitoring and charging is a pretty reliable source of power whether it's a pair of 6v or a single 12v. These are essentially the same aside being connected by cables vs encased in a piece of plastic.
Could one 6 volt battery fail completely and render a 12 volt system unusable? yes, but I don't think it is any more likely than a 12 volt battery losing individual cells.
Again, if they are comparing group batteries to a common GC2 then it's more like that the group will fail before the gc2. To make a true comparison they need to compare a true deep cycle 12 volt which might be something like an Trojan SCS225 which is an expensive battery when comparing amp hour to amp hour. If gc2 wont fit than us gp and there is nothing wrong with them.
