6v GC batteries vs cheap 12v sorta deep cycle
The more I learn, the less I know. :) Or, a little bit of knowledge is dangerous. So I am wondering if GC batteries are truly better than cheap "Marine/Deep Cycle" Group 27's or 31's for everyo...

I have done it with both types (6s and 27DC) doing 50-90s for several days in a row (five or six 50-90s in fourteen days was the longest.) While camping they perform the same per AH capacity for draw and for recharging to 90%.
The difference is when you get home and try to get them back to 100% SOC before they go on Float. It is agony trying to get those 27DCs back to 100% using the required "top charge." They don't gas much and take a long time and it is just a huge PITA.
The 6s OTOH, charge right up and take a shot of Equalize on the VEC1093DBD, and it's all done. So simple!
That was it for me, no more 27DCs ever. I have not got any experience yet on that "recovery" aspect with my used true deep cycle 12v golf car batts (T-1275s) I just got for free and dished up, now trying them out while camping. I hope they are not a PITA too like those 27DCs.
