From my own experience, JPEG quality and compression efficiency can differ a lot depending on the encoder implementation. It would make more sense to compare specific encoders rather than formats in general.
In 2014 (WebP was released in 2010) Mozilla claimed that the standard JPEG format is not used to it's full potential [1] and introduced mozjpeg project that is still being updated [2]. I wonder how it compares today with current WebP implementations.
