We had a friend of ours who worked at Gillette when they first started coming out with the multi-blade razors and it was a big marketing gimmick. So we got one and it really was much better.
I have a Venus and it seemed OK - but somehow we were going on a trip or something and got a bunch of disposable ones for the trip and I just kept using them. I didn't really think about it other than a vague thought that they would be sharper and easier to use somehow. Which I admit makes no sense

So I'm going back to the Venus shortly as soon as I finish off these other ones.
Aha! Yours is a five blade! (I just looked it up). Mine is only a three blade. Maybe I should try it - it's really that much better?
