I really don’t think there are any I feel that comfortable comparing myself to completely, but that is probably true of anyone, when asking a question like this.
That being said I think based purely on personality (and the fact it is kinda the only nerds being portrayed on TV, that I watch, anyways) I kinda relate to Leonard Hofstadter (me and a million other nerds, right?). I feel like I am a self-aware nerd, much like Leonard. He sees the world around him and realizes his place in it. He wants to fit in so, maybe, tries to avoid initially letting people know how geeky he is, but eventually it all comes out. The other characters on The Big Bang Theory, the other nerds, really don’t see themselves for who they are most of the time… a bit delusional.
Leonard has a tendency to whine about situations and I guess I can get that way too. The “why me” syndrome. Not to any kind of extreme but it sneaks up on me sometimes.
I definitely differ from Leonard in the fact that I like sports and understand them… and very loyal to my sports teams (the home town teams). That is often the way I fit in with non-geeks… talking sports… lol.
