I upgraded from the round model to the "Cabo" rectangular job.

The best thing about the round one is that you can cook a small frozen pizza on it.
Worst thing is that it cooks HOT. Not much in the area of temperature control and seemed useless with the lid off in all but even the most windless days.

The rectangular Cabo model seems to allow for better temperature control and the hinged lid is a double edged sword. Easier to use but won't shield the wind when it's blowing vs. you can angle the round lit in any direction.

But, I see the new round one has a hinged lid.... hmmmm that could go either way....
