For me, much of what contributes to a good shave is not only the blade but how aggressive the razor is as well. I don't know this to be the case but I wonder if your razor is too mild to be effective for your beard and shave technique with other types of blades.
Feather's are renown to be extremely sharp so they can really add some oomph to a milder shaver like the Feather Popular or Merkur 23C.
