Okay... well, if we're talking about more than just paladins...
1) Paladins
2) Rakshasa (very strong, especially with the "no retaliation" ability)
3) Cave Lords (spellcasting and the "vampiric strike" ability)
4) Undead (I just like them...)
5) Shadow Lords (they're beautiful, but not very effective in battle)
6) Jarls (I can't really say anything particularly good about them...
7) Ents... I haven't gotten to them yet....
