Re: Which actor looks the most like Superman to you?
Its a bit like asking which of these looks the most like Superman:
They're all "Superman" but not all of them look like the same guy except for having dark hair and a blue and red suit.
If I were to mix and match I'd say Cain looks like the Shuster Studio versions from the early forties. (top and center left.) The Byrne version ( third up from the bottom right) was influenced by Reeve. Alyn the early Shuster version. ( second down from the top left) Reeves, I dunno. He never looked like any of the comics versions to me. The other guys? Never paid enough attention.
The boring one, the one with Khan, the one where Spock returns, the one with whales, the dumb one, the last one, the one with Kirk, the one with the Borg, the stupid one, the bad one, the new one, the other one with Khan.
