My former commuter bike had a double-legged kickstand, and it was very useful. But I absolutely hate the single-legged kickstands. I've had my bike fall over many more times using one of those than when I use no stand at all. My girlfriend's bike came with a proper kickstand plate and a Greenfield style stand. She's only had the bike for a month and I'd estimate it's fallen over at least 30 times. I finally got tired of watching her struggle with it and gave her the double-legged stand from my grocery bike. I've also found that bikes with drop bars are much easier to securely lean against walls than bike with other types of handlebars.
