Awarding degrees in the fewest years shouldn't be a factor of consideration, especially in the sciences. A PhD takes as long as it takes - if they hurry their students out the door, they're graduating people who can't find jobs - don't have enough publications, haven't established themselves in the field, haven't done a rigorous piece of research, haven't made connections. Sometimes taking the extra year or two to ensure a great postdoc is worth it.
I think you should be considering other things - what's the atmosphere like? Some very competitive schools can be miserable to work at. Do the grad students socialize? How are their interactions with their advisers? Don't choose a possible adviser based on how they look on paper - I did that the first time, and had to switch fields and schools to get away because we got along so horribly. I have a great adviser now, but I'm glad I finally learned that how the faculty and students interact can make or break your career. Go visit some of these schools and talk to students.
