I don’t know if anyone else has been tracking this recently, but a while back I got curious about the relative proportions of dh(1) and CDBS in the archive, and started running some daily analysis on the Lintian lab. Apologies for my poor graphing abilities, but the graph is here (occasionally updated):

debhelper statistics

Although dh is still a bit behind CDBS, the steady upward trend is quite striking - it looks set to break 20% soon, up from under 13% in September - compared with CDBS which has been sitting within half a percentage point of 25% the whole time.

Incidentally, was that an ftpmaster trying to sign his name in the graph over Christmas or something? :-)
