Cool, you have a lot more people to worry about heating than I do ha! I personally use this one (Amazon - $57) because there's 2 people at it and it folds. The legs are wobbly and need some fixing before use though. Still a good option is portability is very important.
But for bigger groups, I see a lot of people using custom ones similar to this (Amazon - $87) since they are deeper and throw more heat to the sides. They do seem to let out a lot more floating sparks as it settles so these might put small holes in nearby tents if you add a lot of wood.
FWIW my next one will probably be this one since it has a top and opens from the side - easier to add wood when it's burning hot imo! Plus it still has those little ports for foot heat. I just wish it was something other than woodland creatures cut into the metal ha.
Good luck!
