12/13/12, 12/12/13 or 11/14/13? I know these IVs are far from ideal, but all are hatched (they never spawn in my area) and will reach the same level. My guess is the third because 84% is slightly higher than 82% and the IVs are more defensively oriented.
Checked with a PvP IV calculator and they’re, respectively, #2443 #2130 and #1913 for GL, so yes, the 11/14/13 is the best out of the 3.
Honestly? None of them.
All of them are below 95% of max stats, and typically you don’t bother with anything below 97%. (if it makes you feel any better, the top hatched one ranks at #534 with 96.86%)
I’m actually surprised you didn’t get a ton of them during GO Fest.
It sounds like you would need to use RC as well. It’s not worth the resources to evolve/power up/2nd move a bad one and use it for 1 or 2 days before switching to UL.
