Any snare can be used as a main snare, as long as you are happy with the sounds that you can get from it. A snare drum is one of the most important parts of the kit, and along with the ride cymbal really makes up a drummer's "voice".
Just remember two things:
1. There are no drumming "rules". Do what you want.
