Semantic arguments aside, I have used both the straight feat system and the talent tree and feats system. I have enjoyed playing either way, here is an example of how I'd construct the trees.
Arcane
Path of Learning (Wizard)
Path of the Mind (Psionic)
Path of Nature (Sorcerer)
Divine
Chosen (Paladin)
Clergy (Cleric)
Nature's Protector (Druid)
Warrior
Fury (Barbarian and other rage/fury based characters)
Guard (Fighter)
Nature's Guardian (Ranger)
Rogue
SpellSong (Bard)
Thief
In two more breaks from tradition, I'd have some universal talent trees and have prestige classes use talent trees. For example, a couple universal trees:
Tree of Riding
Tree of Weapon Mastery
