Not exclusively but I used to til I saved up money for a WSM.
It requires a lot of grill sitting at first due to messing with the vents to get the proper temps, and a lot of charcoal refilling. But once you do it enough, you’ll know when/how to set the vents.
The only downside of smoking on a kettle is if you want to smoke a lot of meat. You can barely fit 1 whole brisket in a kettle as it is.
