We use the Coleman Road Trip and it meets all of our cooking needs.. The Weber Q Series probably has a better seal with its tight lid etc... Some folks like that idea for better heat distribution in the cooking area...
I like the Coleman Road trip for all of the accessories including the nice stand etc that can be purchased for it and all fits in a nice roll around two wheeled tote...
The Coleman Road trip runs off of a single 1LB propane canister and has two burners... Also has a water reservoir around the burners in a tray that makes for very easy cleanup...

We have been using our setup since 2008
