User blog comment:MrPacheco101/Old School Brutality: Godzilla '54 vs. Gigantor/@comment-2217541-20101007235118

Personally, I'd have to go with Gigantor. Remember folks, this isn't the Godzilla we've all come to know and love. This is a separate beast altogether (the "true" Godzilla didn't appear until the sequel), one that is not experienced in fighting other monsters/mechs, and was killed by human technology.
