Might I offer the (biased) ranger responce? Please take my opinions with an apropriately sized grain of salt. Personally, I do think the rangers are ranked a bit too high (I'd have them around 8-10), but I'd take their prospect pool well before I'd take Vancouver's (no offense is ment here, Vancouver may well deserve to be higher than they are.)
Not that I mean to complain, but are the Rangers at #7 a little high? Just looking at their writeup, they sound very similar to the Canucks, ranked far below at #21.
Goaltending:
Montoya vs Schneider
Montoya was drafted 6th overall in the 2004 draft, Schneider 26th. The #1 American goalie prospect vs the #2. Both are stuck behind elite NHL goalies on their teams, and need a trade.
This is irrelevant to their rankings.
Montoya has an edge of course, but not enough that its a sure thing he'll be the better goalie in the long run. Just as long as Schneider signs that contract and goes pro.
Of course it's not a sure thing, there are no sure things when it comes to prospects, but as of now Montoya has put in two very good years in the AHL while Schneider has yet to play pro hockey (I realize that this is his choice, but the point still stands.) Alot of good hockey people will tell you that the biggest step in prospect development isn't AHL to NHL but amateur to pro. Montoya has already made that step with flying colors, right now he's alot more valuable.
Defense:
Staal, Sanguenti, Girardi, Pock vs Bourdon, Edler, Koltsov, Rahimi
Staal's a safer bet right now, but Bourdon was drafted 2 spots ahead, he could be just as valuable as Staal, though in a different sort of role. But to balance it out the next 3 are easily better on the Canucks side. It might actually be better to compare Edler to Staal, and Bourdon to Sanguenti.
The consesnsus is that Staal is one of the top 3 defensive prospects in the world right now. His post draft resume is just impecable, while Bourdon has been suspect at times (though I realize that it's hard to judge his performance this year, on account of him being passed around like a drunk freshman at a frat party.) This doesn't meen that Bourdon won't end up the better player, it's possible, but right now Staal has just done alot more.
You can kick Pock out of that mix, he probably doesn't fiqure heavily in the future of the Ranger defense corps. Replace him with Sauer, who is a much better prospect.
I'll give you Edler over Sanguinetti or Sauer, for now, but Girardi is already a steady NHL defensemen (as evidenced by the amount of icetime he was trusted with in the layoffs), Koltsov and Rahimi are not, and we have no idea how Koltsov's game will translate to the NHL.
so:
Staal(the best prospect in either organization)>Bourdon
Sanguinetti<Edler
Girardi>Koltsov (I'm sorry, I need to actually see somthing out of Koltsov on north american ice)
Sauer Vs. Rahimi? I honestly don't know enough about Rahimi to comment on him. Sauer has been exceptional as a shutdown defensemen in the WHL over the last two years, he's a real nice prospect.
Ivan Baranka is also a nice defensive prospect that should be considered.
Offense:
Bourret, Dawes, Immonen, Dubinsky vs Grabner, Raymond, Hansen, Simek
Some second tier offensive prospects, nothing spectacular.
Now I'm not the sort that complains, but like I said the two teams match up well, sort of like the Rangers being a 1A with the Canucks a 1B. Should they really be 14 spots higher?
1. Immonen is not a top 5 prospect, or really of any consideration at all, he's done. Replace him With Callahan, whose abilities where well shocased in the post season.
2. While these guys are probably nothing more than second line talents, it should be noted that you could replace a few of those names with Anisimov, Dupont, Korpikoski, or Pyatt and you would still have a nice selection of second line talents. The Rangers may have only second/third line foward talents, but they've got about 8 legitimate ones (more if you want to include grinders.) Some will bust, but the more bullets you have, the better chance you have of hitting.
I will admit that Grabner probably has the highest potential out of the entire group.
Overall I just think that the Ranger's system is deeper and more comprehensive. On top of that, they have the best player in either group (Staal.)
