Hi Rob.
I have a cobb and as Andrew says it is a pain to clean so I have found I use it allot for doing stuff like roast chicken, food that can be done in a foil wrap, basically no cleaning up after the cook. Salmon in a foil wrap with veg is great. And again if your not needing it for a boat where the base stays cool then the go anywhere rectangular grill is a better choice for grilling. By using both together you can actually cook a decent amount of food. The other thing about the Cobb which is great are the cobb stones that light in minutes which are particularly good when your wanting breakfast on a camping trip. Hope this helps.
Cheers
Alan
