To choose between two tests, you should first take a timed full-length practice test of both. Then you can choose which test is a better fit for you. Content and question style are very similar, but other factors like how you handle time pressure and what types of questions you find most challenging can help you choose. Since there isn't any favor for either standardized test in most colleges and universities, you can choose freely between them.
