To each their own and some folks seem to like these propane firepits.
But I've never found our gas fireplace in the house to be anywhere near as nice or comforting as a real fireplace (although certainly more thermally efficient, especially when the fire isn't going!).
When camping, we want the real thing. We deal with enough fake stuff while living in the modern world. We spend a lot of time outside when camping and appreciate a real, crackling and warm fire.
As I said, your opinion may vary and you are certainly entitled to it.
