Phil, Haley and Melinda were my 3 favorites of Season 6. Although Melinda has the most vocal talent, I think she will go another direction.
Haley definitely has potential and was way better than given credit for (Kat comparison/backlash). I had hoped she would make it to Country week and missed by one week.
Phil seems to be the most cut out for Country overall, but I would'nt mind if they all were successful.
