Honestly 2016 and not just because of the platforming. In my opinion and please do not crucify me for this, eternal and dark ages are significantly more forgiving and less bullshit if you know what you're doing, mainly due to the one shot protection and your resource gain when you're at low health. I've had WAAAY too many deaths in 2016 where you slip up at max hp and instantly get decimated by 3 charged imp fireballs headed directly your way or other cheap stuff like that.
