6 max versus full ring - Wheres the money?

[T-REX]

Wheres the most profit per hour? 5/6 max tables or full ring tables.

Consider every aspect, hands per hour, rake back, number of tables you can play at a time and any other factors.

Also what other advantages and disadvantages are there to consider? For example downswings are expected to be higher at 6 max.

Feel free to comment on whether you exclusively play 6 max or why you do both.

Who plays 6 max and full at same time, tables of each both open.

Is there a disadvantage to sticking to one type of game?
