I've been using a new WebKit-based browser called Orion. It is super snappy, has compatibility with Chrome and Firefox extensions, has power-user features built-in, is privacy focused (collects 0 telemetry as a tenet -- they are donation based), and continues to add features at super fast pace. I highly recommend giving it consideration if you are looking to move away from Chrome.
Some features I love: tree-style tabs. cross-window pinned tabs. low power mode which auto suspends tabs. in place editing of websites. profiles are their own application instance. extensions work on iOS. per-page user-agent. built in notes. preventing auto-playing videos. all this while retaining a native macOS UX.
