...and I have to admit , i've never used one....
I think that sums up a lot of it right there. You may want to actually TRY a product before you review it. Just a thought... 
Not if it looks like it's gonna take away half my scalp ! !
I started with the HB and I have tried my fusion, and I'm cordinated enough to keep using the fusion, the HB is so much easier to work around the skull. but as so many have said its just a matter of what works for your head type and skill level.
My initial impression when I opened up and used the HB was "Damn, I can't return it now". However, with time, I got used to it and now can use with great results and few, if any, nicks. Just because it worked for me though, doesn't mean that it will work for everyone. It depends on your head shapes, etc.....
Bottom line, use what you feel comfortable with and what gives you the closest shave.
Whatever you use, just keep it SLY!
