The Human Alliance Transformers are better in design (typically), and they are bigger than their deluxe counterparts. As well you get a human figure. The figure isn't that great, but can fit within the vehicle for fairly proper scale.
I think the Bumblebee HA is the best so far. Skids is second, IMO, the Sideswipe.
I do hope the other Constructicons are made into Vehicle/Robot form. There are still a few that are only parts of Devastator and haven't been made into robot form yet.
