You should definitely go the freemium route. There are so many games out there and the variation in quality is so wide that I can't justify to myself spending a cent. I have so many games on my phone (most are free) that I formatted it and started over. Unfortunately, you aren't EA or Activision, you are relatively unknown and people have a hard time giving something a chance when there are so many options around. Ad-supported may not be optimal but atleast you get it into people's hands (and earning a few pennies is still better than nothing). Use that to leverage people into buying your future games.
