I suppose it depends on your use patterns, but I've usually taken advantage of Enterprise's 50%-off Friday-thru-Monday special, which works well when I need a nicer/larger car for a weekend. They've also fudged it for me a few times, so I've picked up a car Saturday and kept it at the weekend rate until Tuesday. Also, between most major credit cards and most car insurance covering rental damage, many people don't need to pay for the damage waiver. I could see how Zipcar would be great if you live in an area where a car is optional, but Enterprise has been fine for my limited rental needs.
