I have both installed and haven't noticed any issues. I mostly use Flex Builder 3 as it can target both Flex 2 and Flex 3 SDK's. The only time I've used Flex Builder 2 recently is when I found a bug that only affects projects created in Flex 2 and then migrated to Flex 3--other than that I don't see any reason to use Flex Builder 2 (when you publish for Flex 2 SDK, it even uses the old compiler).

I've got some projects going on in Flex 2, but I'd like to try out some of Flex 3 new feature and I don't wish to uninstall Flex 2. Are there any known issues on doing this? TIA, Guido.
