The same can be said for a grill.
Yes but also no. Smoking isn't about cooking food, it's about introducing flavour. You need to figure out the right type of wood and the right amount of smoke to complement whatever it is you're smoking, and it's very easy to get either or both wrong.
Grilling is just cooking food over a flame rather than having a pan in between the meat and the heat. It's nothing like as difficult to do well.
