Air movement?

Is it better to have one big fan in a tent blowing large amounts of air in one specific direction, or a couple small ones going in different directions?
I'm in a 4' x 4' tent and have a 36" tall oscillating tower fan, but it has a small degree of rotaion, and then a small 6" fan blowing at canopy height in one direction....
I'm thinking the one larger fan will move more air, but I think I like the rotaion of the tower...
The box type one I'm thinking of is 28"...

Big fan + a couple small ones ; ) ; )

One of these on the floor gets it going.... 11,000 CFM.

I use one fan pointed towards the ceiling.
You just gotta push some air and in a 4x4 its easy.
