I'm a Zilly guy. I've never really considered anything else, though I would probably choose something very different rather than a similar company. By this, I mean I would probably go with Paiste or Meinl rather than Sabian.
Playing Sabian's for a long time... HH Manhattan Groove hats; 2 - 18" HH Manhattan Rides; and a 20" HHX Manhattan Jazz ride... I like them but I also think that I could be happy with similar weight/style Zildjians - Crescents - Istanbul Agops and so on... I like dark, thin cymbals!
We all have our preferences... when I started out it was Zildjian's - all A's from Drummer's Paradise in Toronto - later to Sabian AA's - now as I age - dark, thin cymbals - no hi-pitched pings!
