For you, is the paladin a unique concept in and of itself, or is it a broader concept like the cleric?

A player in my game played an Anti-Paladin from 1e Dragon magazine long before any PC played a straight paladin. I really like having variant paladins and the general concept of various divine powered warriors.
When I see variants that are different from the chivalric LG knight I don't say they are not paladins. I consider Green Ronin's Unholy Warrior class a paladin type class, for example.
I also would be fine with an evil blood war paladin designed to fight enemy fiends with no class power changes besides the paladin alignment requirement and code. Anyone can have reasons to fight evil, including other evils.
As a player there is a lot about the specific paladin concept or mechanics I don't like so I usually seek out alternative variants.
For me, bring on the variety.
