Without having tried the Guerilla personally I agree with
@alfredus that the WR2 .95 (standard) isn't as close a shaver, with the WR1 .61 (standard) my favourite of those I was lucky enough to trial.
Ideally I'd happily grab the WR1 standard SB as its so far the best shaver I've tried (until the Rocca V4) and I found the WR2 head wasn't as nimble for under the nose nor shaved as close for my beard growth meaning I'd need to grab 1.25mm+ and even then there's no guarantee it will shave as good as WR1 or Rocca...?
The beauty, pardon the pun, of the Wolfman is that the design provides for a super smooth and comfortable shave no matter the direction so it doesn't surprise me that there exist crazy blade gaps but as with much of this hobby, YMMV and unless you try all the different combinations you're stuck taking a guess and in this instance a very expensive one.
I have read some good reviews of the Lupo and understand the appeal but having owned other offerings from this vendor I'm yet to try a razor that screams "keep me" and I don't begrudge anybody waiting till crazy hours in the morning so they can grab the latest release of the Lupo.
