heh, I am partial to the ones I wrote.
Quasi-Classes (which has a 2nd release coming one day)
BF-Quasi-Classes-Supplement-r2.pdf
Additional Fighting Subclasses (which is essentially ready for release, takes subclasses out of first quasi-class release and adds more)
BF-Additional-Fighting-Sub-Classes-Supplement-r1.pdf
Of course, these are versions that are used in my own campaigns/houserules. Between the two documents I have essentially all the fighter flavors covered. Paladins (through Holy quasi-class), Barbarians (quasi class), Rangers (subclass), Cavaliers (Knight subclass), Duelist/Gladiator (light armored warrior), and more.
One can even combine features for even more individuality... Conan (Barbaric Gladiator), Robin Hood (Archer Rogue, or Archer Ranger)... loads of combinations before even considering Combo-Class characters.
I also use other sub-classes such as Illusionist, Druid, Fey-Mage (unreleased as well), Necromancer (well, for NPCs), but this thread is about Fighter Options.
