I think ip12pro is better buy because of 6gb of ram compare to 4gb on ip12. More ram equal to much longer support for ios. Plus its only 800 bucks more from the ip12 (128gb ver). Classic case with 6 vs 6s, later model until now still support ios14 because of an extra ram it got. If you buy with your telco, ip12pro is a no brainer choice.
