The Battle of the Lexes!

Hi everyone, I've been on a Superman kick this past year. I've always had Superman the movie but this year have started watching Smallville and bought the series Lois and Clark and Superboy. Of them all, which do you think has the best portrayal of Lex?

Here's my list, from best to worst:

Smallville--Michael Rosenbaum
Superman Returns--Kevin Spacey
Lois and Clark--John Shea
Superman The Movie--Gene Hackman
Superboy--Whatever his name is.

Notes. I really almost like Rosenbaum and Spacey equally. I might like Rosenbaum better because his character is more developed and I've been able to watch his evolution into evil Lex. But I can easily see Rosenbaum growing into Spacey's Lex.

I didn't like John Shea's look, but I thought he did a decent portrayal. Despite his being so far down in the list, I did like Hackman's Lex. But after seeing Rosenbaum and Spacey I feel they more accurately capture what how I've always envisioned Lex. The guy on Superboy is the worse Lex on the face of the earth.

What do you guys think?
