People will tell you which is 'best' out of Remo, Evans or Aquarian, but don't believe any of them. They are all good- just choose the one which is best for your ears. Basically, the Remo coated ambassador is the brightest sounding one of them. The Evans sounds darker and the Aquarian one darker still. The Remo one has powder coating which starts to chip off almost immediately, and could be annoying. The Evans ones last longer, and the Aquarian coated heads are bulletproof- they last for ever. However, what I realised is that I don't mind the chipping because I much prefer the brighter remo sound. By the time loads of the coating has chipped off it is time to change the head anyway because it has started to stretch slightly in the middle.
If you are a hard hitter, and don't want a darker snare sound, go for the Remo CS coated head- it is basically one of these with a black spot stuck underneath which stops the stretching and more than doubled the life I got from a head when I was in my 'rock' phase, with only a marginal difference if feel.
I love these heads, and I can't imagine ever changing to another one having experimented with most of the available options.
