The blue and green colors are great; they look good together, are unique to the Canucks (now that the Whalers are gone), and are representative of the northwest coast.
The stick-in-rink is good as a secondary logo but doesn't have enough flavor or personality for a main logo. It's a generic hockey stick and rink that any city with a hockey team could wear. Sure it's simple enough for a "classic" look, but that doesn't hold much weight in my opinion, for 2 reasons: "simple" is not even necessary for a classic look (Detroit, Chicago), and much of the love for these older logos is because of the history connected to them, not for the standalone emblem. It's been my experience that people less familiar with hockey don't like the "classic" logos as much, suggesting much of their value is imparted from the history. I feel that Vancouver can get the same effect by not drastically changing it every ten years, just give it time. The team has had more success and fame under the current logo than any other; changing it now will only hurt brand recognition.
The flying skate suffers from the same generic-ness; people are wearing nostalgia goggles regarding this one, and that's fine, but the logo itself just isn't that great.
I also don't like the Johnny Canuck logo. It's comical looking, no one will recognize it outside of BC, and in general people make poor sports logos in my opinion.
The orca is easily my favorite. The orca is the world's apex predator (after humans); seriously, no animal is more badass. This thing is massive, extremely intelligent, hunts in packs, and eats sharks and freakin' polar bears for breakfast. It also has a strong connection to the northwest, unlike anything in the other Canucks logos. It's aggressive looking and done in an art style unique to the region; all in all a perfect symbol for a northwestern hockey team.
The corporate argument makes no sense to me, every professional sports logo will be "corporate"; the Canucks ARE a corporation, not a high school or community-league hockey team. Maybe someone who feels this way can explain it to me.
The orca is also much more marketable in my opinion. I live in the states and not everyone here is familiar with hockey. From personnel experience, everyone I've talked to who isn't familiar with the history of the sport or the team has overwhelming preferred the orca logo over the others. I feel these people are more qualified to give an objective assessment of a logos value as an image than those who are perhaps too emotionally invested in past cup runs. For those who feel a historical perspective is required in evaluating the logo, I still feel the orca is the strongest choice; as a I already mentioned the team has had more success and visibility with the orca than any other logo.
