I took out my plugs to get them ready for the fall season today and couldn't help but reminise about each one as I checked the hooks and shined up the plug. I wasn't actually thinking about individual plugs, except for the ones with bite marks on them, as I was the color and how well it produced fish. I thought I'd pass on some observations:

Blue herring bone mag wart was a favorite for salmon. I prefer it over the blue pirate which also works well. Kings hammer the green mag wart with the blue, red and yellow underbody. However the gold wart with the red bill and the black stripe down the back is my plug of choice for kings. Don't overlook the purple mag wart! It did well. When chinook have seen a lot of plugs (and even when they haven't) the white hot shot with the red bill is a killer. I've got a "bubblegum" colored plug that has so many bite marks on it it is half white. Both chinook and steelhead love that one.
A good plug to use in glacial colored water for kings is red and black mag wart. I tried a clatter tad for steelhead this year and did real well on it. It was metelic pink with a black bill. My favorite hatchery steelhead plug has to be chrome and red mag wart.

Wish I had this info when I first started buying plugs, might have saved a lot of money. But then again, like most fishermen, I would have experimented with everything I could anyway.
