To be very straight: do you still feel confused or betrayed by the rules of d&d 4rth edition? Do you still think that a wizard should be more... "magic" and a warrior less... "card-tapping-dependant"? I am a believer of the 4rth ed, but I do have been playing it in a sort of limbo, willing to find the core of the game but never really feeling like I was getting nearer to it (to the point you completely ARE your pg, I mean).
So what with Pathfinder? 3.5 is back, really back, with strongly differentiated classes, a fairly good bunch of abilities, nice description in every paragraph to let you r-o-l-e-p-l-a-y every aspect of your pg, alot of interesting tuning on the "old" 3.5 rules (paladin are usable in a very rewarding way, every classes gets a curios and innovative rule like for wiz choosing between familiar and bonded object, or for barbarian to have special "moves" during rage, and so on).
In my opinion: Pathfinder get the best structure (3.5), revitalizing it, adjusting classes to make every single one amusing, removing the more frustating aspects (warriors are war-machines and can be proud to be, for example - all of this just tuning a bit some feats, as to say "dogde" now gives you +1 to AC when you are not flat-footed, or cleave: you hit the first target? you can attack an adjacent one... grasp the twist, uh?), letting you created vivid and complete pg - in doing so, you also get some ideas that are taken from the spirit of the 4rt ed... without it's questionable "rules" and math background.
Be happy, buy it - what's more, the adventures are incredibily well written and organized, and "old" 3.5 adventurers are easily adaptable.
Laslty: in ONE BIG book you have player AND master's handbook. And very good illustrations too; believe me, when you open this tome in front of your wanna-be-players, fairy magic start sprouting around, I never had this kind of "magic-portal" sensation since whe first saw the Immortal Set box when we where kids.
