I truly think you should decide what you will use rifle for, hunting or target, what optics you can afford, any caliber preferences if affected, and get what you want. Dont mean to sound tart, but for a one time poster, for me to do market, caliber, warranty, popularity, etc. research on four rifles does'nt trip my trigger. Any "chest beater" owner of just one or two of these, will have to do those things, or do you a disservice.
Am quite sure "someone" here will come along who either owns all four or knows each from unprecedented experience. Whatever is decided for you, good luck and safe shooting.
