I am dead set on a stick burner! When catering you should have people doing setup and people doing the cooking (YMMV). We try to keep stations seperate. For large parties or weddings, I rarely get to cook, I call on Country and also Mista for this. I am too busy doing other chit such as chatting with the client, supervising various stations, tablescapes, etc.
Of course this is my opinion time and time again, I just think stickburners offer the client something special versus an oven that receives pellets
