I had a bit of a shaving epiphany recently. I was in the US on holiday and a few days in when I went to shave, I realised I had brought my Merkur but I had forgotten blades. DE blades in that size are hard to get over there so I went to the nearest Walmart and bought the cheapest Gillete disposables.
I was amazed at how well they performed! My previous experience of disposables was that they butchered my face even worse than your average razor.
I concluded that it was down to a change in technique. I have been shaving with a DE Merkur for a few years now and as a result my technique has improved massively out of necessity. If you get it wrong with the Merkur, you bleed. If you get it wrong with a Gillette, you get a bit oif a rash.
So yeah, if your technique is good then it doesn't really matter what sort of razor you use. Modern razors, even the cheapest disposables are very good. I'll continue to use the Merkur as the blades are much cheaper. My favourite blades, Feather (the sharpest) are less than a tenner for 30 delivered to my door. I get a closer shave with the Feathers on the Merkur, but I can get a quicker shave with a disposable razor and whilst nbot as close as the Merkur, it's more than acceptable.
Technique is key. If your technique is good, the razor you use won't ,make that much difference.
EDIT: I'd just like to say that the King of Shaves Azor is complete ass though. Don't even think of getting it.
