I think the fact Godzilla pretty easily lifts other monsters demonstrates he's a fair bit stronger than Pacific Rim kaiju, as they tend to struggle with such a feat.
Not to say I don't like Pacific Rim, I love the first film.
See it's funny you say that, I quite like KoTM, maybe because I know who Ghidorah is and all that. That, and all the fights were cool as hell.
A lot of people really disliked the film though, sad because it's better than the first one.
