I think it's nice to have some variety but it's important to learn how to use the razors you have before giving up on them. Become proficient with one style and then move to the next, only then will personal preference shine through.
Too often I read accounts of someone selling a razor after three shaves because it just "didn't work", when three shaves isn't anywhere near enough to get to know a razor properly. And constantly buying new gear in an effort to find something that will work isn't really the answer either.
