Keeping in mind that I haven't finished S15 (no spoilers!), let's see;
Sam; Stabbed at the end of S2 (1), turned into a ghost by a psychic (2), killed in the past (3), shot by a hunter (4), jumps into the pit (5), killed by death in a deal they made (6), killed by a vampire (7)
Dean; killed by the Trickster (103), taken to hell by a Hellhound (104 or 1), turned into a ghost by a psychic (105 or 2), shot by a hunter (106 or 3), stabbed by an angel sword (107 or 4), lots of pills to stop his heart (108 or 5), killed by death in a deal they made (109 or 6), purposely injected to meet death (110 or 7)
These are the ones I can remember off the top of my head, so if you don't count Mystery Spot, then their numbers equal up
