I have both, but prefer AT evo on lead vocals. I only use it in graphical mode and use a graphics tablet to set the note objects (leaving the scoops and natural slides in tact) AT has less phasing and better quality on vocals.

I do like to use melodyne on Gtrs, Steel gtrs (tuning life saver), and other polyphonic instruments or even multi voices recorded to a group track. Antares charging $64 Just for the 64 bit version when we all were really expecting 64 bit when we bought AT7 SUCKS!!! Most of us had to already spend $20 on jbridge just to continue to use AT.
