Original NTL areas use DAVIC for TV and EuroDOCSIS for broadband.
Ex-C&W areas use DOCSIS for both.

Almost. NTL used DAVIC for STB, C&W used DOCSIS for STBs with provision for upgrading to EuroDOCSIS when this became available.
NTL then used DOCSIS for their cable modem broadband service alongside the existing DAVIC STBs. C&W became ntl and upgraded to EuroDOCSIS, then ntl launched cable modem broadband on the same routers. There the matter rests at present.
There are no technical reasons why you can't do the last step in reverse and launch DOCSIS STBs on the original ntl area routers.
Neither's really better, but it's a pain having both and DAVIC STBs are not exactly easy to buy these days. DOCSIS won the battle, it's the VHS to DAVIC's Betamax. The future, in other words (there's an upgrade path emerging, in fact).
