I use Flex Builder 3 - the Flex platform is pretty elegant and although Flex Builder is not cutting edge, it fits in pretty nicely with the platform. Just watched some clips on labs.adobe.com about Flash Builder 4 (next version of Flex Builder) and there are some nice improvements - they say it can run alongside FB 3 so I'm going to try that now. Excited about the new Flex 4 SDK.
