RE: simple ranking
There is a pretty wide range of prices between the three. If money does not come into the question, I would pick the Sako, if it is the biggest factor, I would most likely pick the CZ. I have a Sako 75, and consider it head and shoulders above the other 2 - smoother action by far, and I really like the stock design. The Tikka is a cheaper version of the Sako - in all respects, especially fit and finish. The CZ is a fine rifle, but not quite as refined as the Sako. All 3 will most likely shoot around MOA or better, so it will really depend on what you want/need and which fits you best.
