Comparisons of Pacific Rim to Transformers are bound to take place because both are essentially humanoid mecha movies. The difference lies in execution, thoughtfulness, artistic appeal and sheer enthusiasm with which both the movies were made. Despite having a lower budget than Transformers 2 and 3 , Pacific Rim's special effects are much better as the CGI robots look and feel completely real. If a comparison is done on aspects other than special effects like story, characters and overall appeal of the two movies, then rest assured Pacific Rim outperforms Transformers by many parsecs ;-)
