I'm not going to say it's my "favorite" but the Funkstill Filter Threek is definitely the most versatile filter I own. It can take a little more work to get where you want to go, but that's because there are a lot of ways to tweak the sound. If you like options it's got 'em. You'll probably want to keep the manual handy though if you're new to it or haven't used it in awhile.
