I suspect Vaszily isn't necessarily a bad ref, because while I don't much care for his work, I can't really pinpoint anything.
Amplifying on what someone said above, Missy Barlow is not particularly popular with anybody. Has always been thought of as a great ref, but I've never been able to find what makes her so good.
The rest are all experienced. Historically, Gulbeyan has been among the referees that work the most games in a season, for whatever its worth. I admit I'm a ref watcher - so, again for whatever its worth - I typically like Bird, don't think as highly of Hall, but don't think he's awful at all, and will say that Adia vouches for Pantoja, who was her teammate at Arizona and does have a sterling reputation.
There are a small number of officials that make my heart drop when I see them officiating a game I care about, none of them are on the list. I suspect they all do there best, and I'm not questioning their objectivity, but when you watch a lot of games, some refs just seem more impressive than others.
