> would prefer to buy a Fender strat
I don't think that's true at all. A strat ("strat style" or "s-style") is a shape and configuration. Many of the non-Fender strats are perfectly fine guitars (I have one) from major manufacturers like Ibanez, ESR, Jackson, and others.

Those mostly do not look like copies; they have slightly different shape, the jack is located in a different place, Ibanez has shaper horns, the pickups are different, many do not have a pickguard. However, PRS Silver Sky looks somewhat close to the original to me, although it has a different headstock.
What I meant by "copy" is when it looks exactly the same.
