"Best" depends on how they are used by the individual. What is best for you may not be best for another, thus your question is impossible to answer.

I'd be using them the same way you do.

You have no idea how I use my batteries. Do you boondock? Do you power AC appliances from the batteries with an inverter? Do you have a residential refrigerator?

By far the majority of all RV owners never camp without electrical hookups. In that situation, just about any cheap battery is sufficient.

Amen ... to all that!

I'd jump in here but I don't want to get sassed at.

There is another type that may be even better called "carbon foam". They can be used in cold weather whereas LI don't do so well.

I would expand on this comment to say that LiFePO4 batteries do require the user to be aware of the temperatures in which the batteries will be used. They discharge well in below freezing weather but they get damaged if they are charged when the battery itself is below freezing. Also, they get damaged if the battery itself gets above 140 F. So you put in a BMS and intersperse heaters within the well-insulated battery compartment to maintain the temp above 32 and you are all set.
