Quarter system is probably good for you because if you chose the wrong major, you'll find out in quarters instead of semesters. If you're on AP (academic probation), you'll find out you have to pick it up after 2 quarters, and then you can either change your course choices or leave the uni.
Quarter systems don't cover less than semesters either. The topics are broken down into 3 instead of the usual 2. Take biology for example. At UC Davis, it's broken down into bio1a, 1b, and 1c... with bio1a being general bio, bio1b being animals, phylogeny, classification,etc and bio1c being plants. Math, physics, chem and most other classes are done the same way.
The UCs (except berkeley) have been on the quarter for so long, that's how the schools and classes are arranged. Problems with teaching too slow, fast, or skimming only occur because the teacher is new to the quarter and doesn't know how to teach to it or is a bad teacher and can't teach in the first place.
