I had an American Deluxe Strat with the S-1, and while it was fun to play around with the tone knobs on 10 different pickup combinations, it is somewhat unnecessary. I've read that the American Deluxe Tele with S-1 can cover ALL of the sonic ground of a typical SSS Strat, however. With that said, I think the modern 5-way switch is the perfect balance. Variety is the spice of life after all, even if I primarily use the 1st and 4th positions. I like the jangle of the middle and bridge pups together, more than just the bridge alone. If I played out, I would use the bridge since it's the best if you want to really cut through IMO.
