I have both of those razors. The blackbird is a couple ticks less aggressive. I can get much smoother with the wolf with the same amount of passes. Both are great every day shavers but the blackbird is definitely the one less prone to hurting you.My preference is for moderately aggressive razors like a WR2 1.25 or Blackbird. A nice, pleasant amount of blade feel, and an easy two pass (with the grain, against the grain) shave.
