With the same size tent we have used 3 stoves thus far.
Box stove, wood burner - required frequent feeding with wood. Didn't throw enough heat for that size tent. Would have been better though if we had some higher BTU wood available or if we had added a few lumps of coal.
Pot Belly, coal burner. More heat, less stoking. Still needed too much feeding, dirty, and hauling coal is a nuisance.
Cylinder Stove. Best so far. Flat top surface is very nice to have. Pretty well suited for a wall tent. Still needs frequent stoking with the native soft woods. Way better with higher BTU woods.
