1998 Green Weber Mastertouch kettle by far! It has cooked everything cookable
For those who didn't catch the Weber kettle bug until the 2000's, the Mastertouch is very close to the One Touch Gold but it has the lid holder and handle thermometer like the Performers of the era.
A close second is my 2007 Smokey Joe Platinum (Jumbo Joe). I bring it on vacations and make almost all our meals on it. Last year we rented a beautiful lake home for 5 days and I smoked ribs, wings, pork shoulder, and meatloaf on it. I also grilled burgers, steaks, pork chops, and made an egg bake for breakfast.
I love my Webers! My dad and I have rehabed over a dozen kettles and have given them to deserving friends and family.
