I like the Lester cut better. It doesn't make sense for Superman to have to lose hios powers AFTER he has sex with Lois. If he can do THAT, what's the need to be de-powered?
And her attempts to un-mask his identity are creepier. She jumps out of a building and appears to SHOOT Clark. She comes off as a psycho. We also miss the fighting in the Fortress with the Kryptonians(the saran wrap "S" and all that.)
The only big improvement is the inclusion of Jor-El and the way that Superman gets his powers back.
