I don't know what in the UI you find so clunky. They seem extremely close to me. If somebody switched my browser without telling me I probably won't notice the difference between firefox and chrome. Even if firefox was a slightly worse product (which I don't think it is) I would still use and recommend it just for its privacy focused features recently. Non-chromium based browsers break google's 100% ownership of the web experience and gives some leverage against undesirable change. So even those are better. On Android only firefox supports addons and easy ad blocking.
