There are so many variables I don't think one razor can be better than another really, its all down to personal preference.
I started with a Merkur Futur, which I was told was quite aggressive, I didn't find this at the time, but now I have used a few older Gillettes I know what mild really means.
I have a selection of razors, ranging from an aggresive ICON classic through to a very mild Gillette Tech, neither of which I use as one is too aggressive, the other too mild.
I find with a razor that is too mild or too light I tend to use too much pressure and too many passes required resulting in razor burn, so a bit of aggression is required for me.
My personal favourites are the Merkur Progress and the Gillette Adjustable (Fatboy).
I have a heavy beard, so need a fairly aggressive razor, I also have quite sensitive skin so need to remove the beard in as few passes as possible.
