If it isn't already obvious, Admiral Jean-Luc Picard, opinions and preferences vary widely among Superman fans -- as is probably the case with most franchises with long runs and multiple productions. As TREK_GOD_1 says above, he is a huge fan of Kirk Alyn and Henry Cavill, whereas I would elevate Christopher Reeve and George Reeves and Tyler Hoechlin above either. Which is fine, or at least it should be, because tastes are individual, and different aspects of character and performance appeal to different people. (TG1 and I are in agreement, however, on Elizabeth Tulloch's excellence as Lois Lane -- a character who, to me, is at least as important as Clark/Superman himself.)
The only way to know which iterations will work best for you is to sample as many as possible. One of the joys of Superman fandom is just how many versions of the beloved characters and story there are to enjoy over the nearly nine decades since the debut of Action Comics #1. Personally, I have at least some affection and appreciation for all of them.
