Classic by far, I honestly did not give era a chance at all, and ill admit that. I was excited when i heard it was coming out, but as soon as i played it i thought the map was an eye sore and everyone was frantically running, i also find the non pk zones arnt defined well and blend in wayy to much. After playing for a good 15 minutes i got sick of warping to the hospital and i quickly deleted the app and went back to classic. I have been back to era to check things every now and then but ive just decided over time that i don't like the basic idea of 2d gun games.. So for me iClassic will always be better than iEra
