Although I've not tried the IT's I went for the MM's as I wanted a bit less midrange. IMO the MM have to be the most versatlile strat pickups- superb cleans, will easily do SRV, Gilmore, Blug tones and I'm really suprised how good they sound with silly amounts of gain and dirt. Mine originally had lace sensors which were completely toneless and were pretending to be strat pickups.
