For BFL13 et al... FLA vs AGM vs Li vs heated Li

I realize everyone on here has different electrical req's with how they camp. I don't fulltime and don't camp in the winter and have minimal electrical req's. I dry camp don't watch TV or play on the internet, so basically some lights, refer, WH, and water pump. He kept talking about real world experience and did 20 amp discharge test down running MV's to 8 amp tests and then concluded that LI was cheaper over the life cycle of battery usage. What I would have rather seen was low amp draws "real world" how I use my batteries and how long each battery would last. At $900/ battery for lithium and $90 for 6v flooded that is 10 times the cost. Will the LI's last 10 times longer to recover the initial cost?
