80's Squiers are cracking, my drummer has one, his has all fender parts too, i have a 1999 mexican fender strat and i do prefere it, but i wouldent say that its really better and that its more of a personal preference thing.
But yes mexican fender strats are great, some are better than others, you should try a few until you find "the" one, a friend of mine that im in uni with just bought a black mexican strat with a maple fretboard and its one of the nicest guitars ive played full stop.
