How a guitar pick "feels", is such a matter of individual preference, that there really doesn't seem to be much point in trying to rate them, as what I like about a particular type of pick, may not be relevant to another player.  Most picks have high ratings, because players who like that particular type, write reviews that rate them highly.  Obviously, the best thing to do is playing with a pick on your own guitar, but that isn't always possible.  With that said, for what they are worth, here are my thoughts regarding Jim Dunlop's purple colored, Big Stubby 3.0mm picks.
