Who plays the best Superman or which actor portrayed him best?

Christopher Reeve's portrayal of Superman in the late 1970s and 1980s is often considered the definitive and one of the greatest performances of the character. Reeve brought depth, charisma, and a genuine sense of heroism to the role, defining Superman as a compassionate, noble, and inspiring figure.

Henry Cavill's recent portrayals of Superman in several DC Extended Universe (DCEU) movies have also received positive recognition. Cavill's physicality, commanding presence, and dedication to the character's iconic nature have made his portrayal a fan favorite.

Other actors who have portrayed Superman in popular live-action versions include:

1. Brandon Routh in Bryan Singer's 2006 film "Superman Returns"

2. Dean Cain in the 1990s television series "Lois & Clark: The New Adventures of Superman"

3. Tom Welling in the television series "Smallville" (2001-2011)

4. George Reeves in the 1950s television series "Adventures of Superman"

The choice of "best" Superman often comes down to personal preference and interpretation, with each actor bringing their own unique strengths and perspectives to the role.
