As far as forwards go (unfair to compare Defence and Goalies), I'd say the top order would be:
1) Lindsay - Subjective, but still the whole point is being the most "outstanding" aka. best player in a given year
2) Ross - The single most common way of comparing forwards is how many points they get, it's a big deal
3) Rocket - Goals are the whole point of the game, like the ross, they aren't subjective awards, and you gotta be real good to lead in either goals or points
4) Hart - Too subjective in the last handful of years, players don't get the chance to win this award unless their team makes the playoffs (usually)
5) Selke - Defence is a secondary job for forwards fundamentally, but still important and impressive (see the praise for Bergeron etc)
6) Smythe - Like the Hart, too subjective and 90% of players don't even get a chance to compete for it
