IMO there isn't any one best sailmaker. For custom sails, the results will vary more greatly based on the individual sailmaker/loft. Different technologies employed can make some sails better in some areas and worse in others. The main issue with that could be said that the sailmakers are recommending the wrong fabric or construction if the sail doesn't live up to an individuals expectations(too heavy, loses shape quickly, crap in light stuff) or they're just not putting in enough time and effort into the design and/or build.
One design stuff is a whole different ball game in sail selection. In well established classes the differences in sail shape tend to be quite small. The largest differences are found more based on prevaling conditions of where the sail was designed. After that is comes down to the preference of the skipper... X sail is known to have a very narrow groove but better point where Y sail is a bit more forgiving but points a degree or so lower than X.
That being said... Haarstick for downwind work, Quantum for all else...
