Which Molters to power up?

Assuming I don't catch a better one with my free passes in the upcoming days, I currently have two candidates I can power up. Both are 1855 @ 93.3% but one has 15/15/12 IV's and the other one 15/12/15.

Which one should I power up and why?

PS. Movesets are not an issue as I have plenty of TM's
