I love the term "taste-skill gap". I work with people who are good at making movies and people who are good at making video games. There is always this awkward thing that people who are good in one area are convinced they would be great in the other. I don't think I have ever met a film director that didn't think he would be a great video game designer if he put the time into it and really good game designers (well the narrative game ones) don't understand why they wouldn't be a good choice to direct a movie.

Taste comes quicker and can be more generalized. It's also pretty easy to express. Skill has many hidden components, takes experience to hone and is typically very specific.
