in my opinion:
sage ea: Insolent ancient EA survives more with DPH than def camping eas, harpist ( u can hate on him as much as u want but 10% of target he gets would make u log off), Esok ( original owner = Tobi); doesn't play lately, but was able to outplay ppl with so much better gears.
demon ea: Butthead ( same as for harp, u can hate on him as much as u want, what matters is his skills and survivability not his personality) PiS ( if not the best mass pk ea, mostly solo/duo/trio player who manages to kill more than whole squad itself and survive more than barb; despite scripts he has very huge knowledge and his gameplay is just to watch and learn), Soochi (known for IG spam, but really try to do his thing, just try it, it's not as easy as he makes it look like)
there are bunch of good eas in 1v1 like Geo, Maxy, Stajson, Burrdete etc but the list up was from what I've seen over the years of playing EPW and mostly mass pk related. peace
