My 22-250 has a Nikon Monarch UCC 6.5-20x44AO scope on it, and it is every bit as much scope optics wise as the scope brands you mentioned, with the Bushnell Elite 4200 being a close competitor value wise. This is not to say that the Swarovski, Zeiss and S&B scopes aren't great scopes, but they are MUCH more expensive and don't really offer that much more in the way of performance. They have a lot of "bling" value, but not much more, IMHO. My Nikon transmits more light (rated at 95%) to my eye than it can use, the optics are bright and crystal clear all the way up to 20X, and it cost me about $400.

If you were to consider only the scope brands that you mentioned, then I, personally, would buy the Elite 4200 even if I could afford the more expensive alternatives, and use the money I saved to buy reloading components and equipment for it.
