Which are the better versions of the first two Christopher Reeve Superman movies?

We all know that multiple versions of the two good Reeve Superman movies exist thanks to… well, a lot of different circumstances involving Richard Donner’s conflicts with the Salkinds, a two-night television event, and some rereleases.

The three versions of SUPERMAN: THE MOVIE are a) the original theatrical release, b) the Special Edition Director’s cut, and c) the made-for-TV Extended Edition. The two versions of SUPERMAN II are a) the original and b) the Richard Donner cut.

Which versions do you prefer, and why?

Superman 3 & 4 are as good as 1 & 2.
