Paladin or Shadow Knight

[Vanessa]

I am completely torn between which one to go, was hoping I could come to forums and get some opinions from you guys to help me make up my mind. I know they are both basically the same class with just small differences right? As in, Pallys use Flash of Light while SKs use DC, Pally armor is white and SK armor is black, Pally have LoH SK have Harm Touch etc

But what are some of the bigger / more important things I am missing here because it seems like there is hardly any Paladins on this server, and if they are so similar to SK's then why is it that there are like 10x as many SK's as there are Paladins?

Advice / Info / Opinions / Suggestions wanted! Thanks!
