Probably the worst inking combinations I'd ever seen were at DC in the 1970s:
Walt Simonson and Jack Abel on Legion of Super Heroes and
Marshall Rogers and Vince Colletta on Mr. Miracle.
In each case the inker removed much of the style that made the penciller a superstar in the first place (and in the Simonson/Able case, the inker rendered the penciller's usually distinctive work unrecognizable).
As for best:
The gold standard has to be Adams and Giordano.
