The Henson way is to lock you into an angle. They are also very lightweight.
The lock-in guarantees a good to very good shave every time.
The drawback is that you can hardly if at all deviate from the given angle. So if you want to lean in and have some stubble somewhere you really want to kill you have to go over as it is till gone.
If you like lightweight and safe and guaranteed success, they are a winner.
If you want some more control and don't like aluminum haptically or its low weight, rather not.
