What's the difference between the new Weber Spirit and Genesis lines?

Verified-purchase reviewers at major retailers and posts on r/webergrills describe the 2025 Spirit line as a substantial refresh with Boost Burners and a Sear Zone, while Genesis adds PureBlu burners, larger cooking area, a built-in grill locker, and higher overall BTU output. Reviewers on smokedbbqsource and seriouseats characterize Genesis as the step-up choice for serious weekly grillers; Spirit is positioned as the value pick within Weber's lineup.
