Best Salt?

[tippmann03]

i've had my tank set up for a year now and i've been using instant ocean salt for the water and it seems to be a good mix to me. however i've been reading little bits here and there about people saying its the worst out there and there are many better types out there. My question is which salt is the best available and why do you think so?
