Big Dawg is right.
When I switched from a Performer to the keg with 2 side tables, I bought a table. I never felt that urge when I was using the Performer. Now that I have a work table seperate from my grill, having side tables is a bonus, but if you have to choose between one or the other and you don't want to buy or build other prep space, I think I'd recommend the table.
Having said that, one of the best things about the Akorn on 3 wheels is how easily it moves around the patio. I can move it with my left hand while holding a plate of food with the other hand. The reason I like it is because I hate using grill covers so I can easily pull it out from under the awning between cooks and put it back when I'm done. That's not going to be as good a strategy with a table. It won't be as hard as moving a ceramic though.
