Probably true for still subjects. Doubt it for motion tracking though.
LensRentals blog had a useful series on this. The result was, yes, CDAF is consistently more accurate than PDAF:

As for speed, the depends on the implementation. Panasonic & Olympus, though, do indeed have single shot AF that's as fast or faster than PDAF.
CDAF is very good for getting you to focus quickly on all my m43 bodies, I don't ever remember a missed focus on a non-moving object. Depending on the lens, you probably could not tell the difference btwn PDAF and CDAF.
But when you go higher end, both with bodies and lenses, the difference is huge.
