This list is non scientific, I selected major leaguers from the top 30 lists from my memory, I did not refer to baseball reference or fangraphs. Remember I was not looking for every player who played in the major leagues, I was looking for players who stuck around for a while.

Who were the Plus teams?
Anaheim's farm system in 2004 had seven players who were part of their playoff run in 2009 plus two others who were traded.
Minnesota had Mauer, Morneau, Bartlett, Kubel, Crain and Span in their top ten and got three pitchers from the "teens', Bonser, Liriano and Baker
Philadelphia had quality, Hamels, Howard and Madson to go with Utley and Rollins who had recently jumped to the majors
As mentioned the Blue Jays had a pretty good group although Werth was traded.
And the minus teams?
The Cubs had only one player from their top ten, Felix Pie, stick in the major leagues.
The White Sox had only two players from their top 30 make it, one of whom is now a Blue Jay (Edwin Encarnacion)
The Royals had a good player in Greinke, an OK player in DeJesus and not much else
The Expos had a weak farm system
The Padres had a terrible system Khalil Greene was the best player to come out of it
How successful are top five prospects?
21 #1's made it but that includes Josh Barfield, Bobby Crosby and Jeremy Reed. Your number one prospect has about a 50% chance of becoming a regular major leaguer.
82 top 5's made it out of 150 named, that again is just over 50%
How about numbers six through ten?
57 players rated 6-10 made it, that is 35 players or approx. 30% less than those rated in the top five.
Among the best players rated six through ten were:
John Lester was rated at #8
Matt Holliday was #9
Curtis Granderson #8
Andre Ethier #9
Adam Jones #9
Who is the best player who was rated outside the top ten?
Howie Kendrick was rated #14.
Jon Papelbon was also #14
Josh Johnson #24
Russell Martin #18
Francisco Liriano #18
Scott Baker #19
Melky Cabrera #19
Mark Teahen #15
Skip Schumaker #29
Brian Wilson #30
JJ Putz #17
Josh Hamilton #16
Jayson Werth #17
Shaun Marcum #21
The big link among the players on this list is that most of them were still in short season ball and had not developed a track record. Four of them had reached AA in 2004, Boof Bonser, Skip Schumaker, JJ Putz and Jayson Werth and as we have seen Werth dropped because of injuries.
The lesson is that short season, or young prospects, still have a lot to show. Once a player reaches high A or AA it is hard for him to substantially improve his prospects for a big league career.
Brian Wilson gets the prize for lowest rated player, but he hadn't pitched professionally when he was rated.
