Fallen Icarus is almost better than Navigator for farming.
AOE attacks all over, but he will not die and is not as hard on any blocker.
Bounty Hunter is a machine in PVP attack, both with his permanent stun on one toon and as an energy powerhouse from round one. He also will not die with the right talis.
After this, it gets a littly muddy, so I'd say Pharaoh maybe, for sentimental reasons. He was my first 5* Eddie and helped me through the story mode early on.
His update was quite OK, of course he is not top notch now, but can still be useful in Gauntlet.
