The most obvious difference between the Spirit and GENESIS lines is pricing. The Spirit line tops off at less than $1,000, while the GENESIS grills start at $800 and venture into the $2,000 range. Spirit grills are smaller, with a 24” grid width, while GENESIS grills go from just under 26” to 34”. Some GENESIS models are WiFi-enabled, stainless steel cooking grates, lighting, and offer the versatility of optional Weber CRAFTED custom cookware.
