Just my opinion, but I don't think you can go wrong with any of the options, whether the strat is made in Mexico or the USA. I've owned many strats over the years, and have settled with my 2002 and 2003 American Series strats. I've owned MIM standard strats and hot-rodded them with better pickups and bridge saddles, and they turned out to be awesome guitars both in terms of playability and tone. The quality of the MIM Fenders is as good (if not better) than some guitars sold at much higher prices.
I've been playing now for 38 years, and bought my first strat in 1983..I've never had a bad experience with a Fender product, whether it was a guitar or amp. It just depends on how much you want to spend. You can always upgrade them to better pickups and saddles.
