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

I ordered the batteries from https://batteryguys.com/, price was comparable & free shipping. The inverter came from Amazon. I think I may have overdone the cable size between the batteries & inverter, I used 4/0 for the three foot run, probably could have used 2/0, but I know I'm good with the larger cables. Figuring out where to put the circuit breakers & how to run the cables was the tough part. Cables that big aren't real flexible.
Oh, and most importantly, my wife's hairdryer uses about 6ah at 50 amps to dry her hair in the morning. So to make 3 cups of coffee, some toast, and her drying her hair, we use 20-25ah each morning. The solar panels put out 10-15 amps during peak daylight, so they charge the batteries back up quickly. And since the batteries are a total of 250ah, using 20-25ah each day is no problem.
