When you say "better," what does that word entail? Are you looking for better dynamics, better control, cleaner interface, ect? KeroVee, GSnap, and a few other free plugs are available. However, I have to say, if you're genuinely utilizing a plug as powerful as Antares or Melodyne, and still not getting the pitch correction you're looking for, I would go out on a limb and say you need to research your settings. They're both neck to neck in the industry standard, and across the board. I prefer Melodyne personally, but it's the internet, no one cares
