Yes! Me and 0xCube created WebShield & wBlock respectively in parallel in close collaboration with each other. They're pretty much sister projects. I do think since I create more free time for myself, WebShield has (some) more features - just off the top of my head: iOS/iPadOS/visionOS support. wBlock does currently have an auto updater for filter lists when you open the app though, which WebShield doesn't have, but I'm working on it!
