Generally, Osprey ridge is considered the best designed course. 4.5 stars instead of 4 like the others.
Enjoyment of the courses also depends upon your game. Magnolia is loaded with sand, palm is loaded with water and Lake Buena Vista has tight fairways that may be intimidating to an occasional hacker like myself. Oak trail is a 9 hole walking course, which I expect to become more busy now that it is included in the water park and more options.
That is generally how they rate Osprey, Magnolia, Palm, and then LBV.
Oak trail is good for warm up, or for going with kids.
