I also like Revan one of my favorites, but he'd lose from a lot of people.
I think the real problem is, when you like somebody you know more about him then other people do and then people would quickly think you are a fanboy. Yeah I think Revan could beat Exar, in a really close fight but I also think Exar could defeat Revan. A lot of people will agree with me and a lot will disagree with me. The only thing is seeing as I know more about Revan then a lot of people here they will see me as a fanboy even though I don't consider myself as one.
The same thing can be said for a lot of other people here who defend people with a passion just because they know more about them then most others and that makes those chars more impressive in their eyes. Thats not really fanboyism either.
You are a fanboy when you really don't know anything and then just say something about them. But otherwise its a touchy subject at best, and both will think the char they defend is more impressive simply because they like them more.
