First things first, I never use a bright jerkbait in clear water, the most I'd go is lightly stained. Second, Husky Jerks have a time and place, but they're not my first choice. They tend to be a lot stiffer, if you will, in action. That is to say they don't have a whole lot of action; they're more subdued. Last is probably cadence.
People throw Pointers, Flits, Squadminnow, and Vision because they work; some say better, others deny that a more expensive bait works better across the board. Personally that's their own brand of justification, nothing less nothing more. When I'm fishing tournaments, I want the best gear that I can afford, that's from rod, reel, line, to tackle, baits, lures, and hooks. All of it. It's not a prestige thing, it's not being a braggart, it's that I'm going to use any advantage that I can get to give me a leg up. Pointers very often fit that bill. They're a great jerkbait with a large variety of sizes, depths, and colors.
I guess, in short, that you really answer your own question. You see a lot of people throwing LC Pointers because they work.
