As I have not been at CB during Easter, I cannot tell you whether its Easter Egg hunt is any better or worse than others. You can go to any resort's Easter events. BoardWalk's are usually pretty good with somewhat of a hunt but also craft events on the walk and usually both a MR and MRs. Easter Bunny. Nevertheless, as a whole (and I have seen many of them) the Easter Egg hunts are about it and I was never really that impressed, partcularly since they are extremely crowded.
One thing to understand is that Disney does not treat Easter like Christmas and thus you will not find it going overboard on Easter. Things at Easter are far more subdued and the time is treated more like just a regular spring break period. MK has an "Easter Parade" but that is just the daily 3 p.m. parade with Easter floats added and that parade goes everyday of the week leading up to Easter and Easter. I would not recommend even trying to go to MK on Easter -- nothing goes on there that day which you cannot see another day of the week -- because just about everybody goes there on Easter Sunday (likely because many believe, incorrectly, that something special does go on there that day) and the other parks tend to have their lightest (but still very crowded) day of the holiday period on Easter Sunday.
