The R41 was probably the most efficient DE razor i've ever had, but somehow the shaves weren't as enjoyable or comfortable enough and it felt rough, tuggy with small blade chatter even with sharper blades. I kept mine for only when I need a fast shave with less passes, but them I've got a MMOC, which is basically an R41 on steroids, but also much smoother and comfortable and I had to sell my R41.
The comfort of the R41 depends on the blade. I tried Feathers and they were very rough, uncomfortable and did not give me a close shave. When I tried Astra SP, it was much smoother, more comfortable and i got a much closer shave.
