Depends on what you are covering.
Ideally, it takes 3 quarter classes to cover the same information in 2 semester length classes - but I'm afraid it doesn't usually work out perfectly. It also gets messy when you are trying to transfer units from one system to the other - unless you only take year long courses.
I really enjoyed the quarter system because you never were bored. I like getting the highlights and moving on. I do understand what you mean about feeling "squished", but I prefer that to the dragged on bored feeling. It doesn't necessarily give you the same depth of information if you are taking a one quarter course versus a one semester course, but if they were year long, you actually would spend MORE time in the 3 quarter courses on a class versus the 2 semester courses.
I think that they are both good systems and appeal to slightly different thought patterns. It just depends on personal preference.
Just my opinion :-)
