This is really tough. You're splitting hairs with a lot of these guys. They are roughly on a par, and it comes down to personal preference. The way I approach this question is, if I were GM of a team and all these guys were available to me at age 18 at the same draft, and I have the benefit of knowing their careers, who would I pick? For me, it comes down to Hasek, Crosby and Jagr. Three totally different players, all dominant for long stretches of their careers, and all extremely accomplished with the hardware. Honestly, I can't even decide among those three. Hasek and Jagr are two of my favorite players of all time. But I think I'd draft Crosby based on consistency over a long career, dedication to winning and the team, and attention to detail in all three zones. He's excellent at every aspect of the game.
Prime Hasek was maybe the biggest individual game-changer ever, but he was also a bit of a weirdo and not always the best teammate. There were controversies where he sat out when people thought he was healthy enough to play. Jagr was a traveling mercenary and the later years of his career were not as good as Crosby's. I'm not sure if that should matter here, but for the moment, I'd probably pick Crosby if forced to choose. Ask me tomorrow, I'll probably take Dom.
