But, in reality, these are my active grills. I rarely use the Genesis 1000 ( with silver B trim ). I've only used the performer once since I bought the WSK. I use both to "hold stuff" since I lack storage and prep space and these will likely wander to new homes over time.

The WSK is the most versatile grill/kettle/smoker I've used. I t sits right next to a performer and the performer sits unused.
YMMV good luck with your journey
