Use the Fat, Luke!
I have really enjoyed my switch from the Merkur heads to the new Muhle version on my Edwin Jagger because it is smoother and less aggressive.
Less aggressive than a Merkur HD? The HD is a great razor for both beginners and experienced shavers, because it is not aggressive when compared to some others, like the red tip, but once experienced, you can get an amazing shave with it. For me, BBS every morning.
I would go with Merkur. But then again I've only tried Merkurs and Gillettes.
