Both companies make good value equipment that ranges from high end optics to what I would consider monkey ward toy scopes. The optics vary from sample to sample but should generally be equivalent in the two you picked. I personally would go with Celestron because I have owned many with good success. My primary astronomy telescope is a high end Celestron ED refractor and it has the best optics of all the scopes I have owned (about a dozen or so).
