The round direct connect units throw out a lot of heat very quickly. They are also hot enough to burn anything that touches the front grill. Ours requires lots of ventilation,& uses a can of propane every 3 days, if left on while sleeping with a medium setting.
The Buddy heater throws less heat, is better protected if tipped, requires less ventilation, & a can of fuel will last a week on low setting.
On our upcoming back country elk hunt, we will use the round unit in our kitchen-dining tent, & the Buddy in our sleeping quarters.
