I really liked the first one, and this one is as clever, although maybe not quite as gripping emotionally.
This story overlaps with turn of the century Hong Kong history and the changes with the handover as well as the internationalisation of the networks (both police and mob) with the changes. This added "historical" connection really works in the film, it makes it more immersive and believable.
Apart from that it is a bit "more of the same" except the lines are even more blurry between law and crime.
