I have a dealer who carries both. I have only listened in a showroom environment. I preferred the Pioneer S-1EX.
IMO, They had better drive and extension. Very clear and transparent. I like the way they propel the music and give it a constant rhythm and flow. They should sound fantastic with the McCormack which I have also owned with Dynaudio speakers. Pay attention to matching your other components. They are quite reveling of upstream equipment. Watch the rake angle as well, they have a built in tilt that may need adjusting to suit your seating position.
The SF was a fine speaker and I cannot fault it, however, it is not for me or my listening taste at this time.
Caveat: Make sure you really like them/keep them. Resale is not that great on the Pioneer branded product. The SF will hold their value.
