To my knowledge, 1Blocker uses the iOS/macOS content blocking APIs, which essentially allow an app to provide lists of content to block to the system, which pre-computes a fast/efficient ruleset for use while browsing. This results in lower energy usage, faster browsing, and more privacy during browsing. Chrome does not to my knowledge provide an API like this, and extensions are still roughly a JS bundle that defines blocking rules at runtime, slowly, using more energy, and potentially having access to your browser history while it does it.
