Personally, i'm neither a propane or a charcoal guy, but I prefer to do BBQ the brazilian way with this pre-burnt wood stuff (carvão in portuguese, I don't even know what it's called in english).
My dad just uses propane out of simplicity. He's a busy guy and generally doesn't have a lot of time to dedicate when the fam has a bbq. I on the other hand when I bbq, like to make a night out of it and do it slow and right. But for the way I bbq I don't need any fancy grill. Heck all I need is a few bricks situated in a square, some carvão and a rack.
Thanks for the comments guys, keep em coming.
