Today I got both Mühle R89 and Merkur 15C razors I had been ordering. Even though I had been shaving with R41 in the morning, I had to try them when I got home.
Which one to try? Both of course
! I loaded Astra SP in both and shaved one side of my face with 15C and the other with R89.
C15 is really the most wonderful razor I have had in my hand. It gave me with less effort a really smooth and good shave. It was much more nice than R89. I still had irritation from the shave in the morning (R41 is brutal), and R89 added a little to the irriation, while I notice nothing there were I shaved with 15C.
There is no question that R89 is better made and of higher quality, but I would even rather pay for two 15C than not to have a 15C.
