I play drums, and always thought that Whitten playing, specially in "Sultans" didn't match with the feeling of the song, he added many toms and crash here and there,.
The most apropiate one, in my opinion as drummer, was Pick, that served the song like the song asks, Terry added more power and speed, but it was also deserved as the song when Terry was playing was more fast and with more energy. The drummers that MK had during his solo career, I think only Danny got to play what "Sultans" needed, the rest did more or less ok, and to my taste, I liked them more than Whitten that, I like him playing with Macca or with Presuntos Implicados (a Spanish band in which Whitten also played).
Pick Whiters was perfect for the first incarnation of DS, Terry was perfect for the rock and roller Straits, and Jeff Porcaro or Manu Katché would had been perfect for the OES tour, but they said no unfortunately.
