Eagle requires better golf, the multiple pars more consistancy. So eagle requires you to make more difficult shots including a put that would likely be longish after coming in with a long iron, the pars individualy are not difficult but again making 3 requires consistency. Weaker senior golfers may not have the strength to put themselves in a realistic position to put for eagle but many i know are very consistant.
So by definition the eagle is more difficult. The pars require more consistantly.
