I find that the Wilkinson stainless seem to perform similar to the RED IP. But Astra and gillette 7 oclock are top notch. If you want super sharp you got to go with feather. I can only get around 2 good shaves out of a feather though ? If you want a killer blade that performs you might want to try Voskhod. This is one of the best I've used so far. Of coarse with blades YMMV.
