andy2004: The question is answered, I'll put that in title.
I knew (and had) most execrunchers mentioned here, it was just a re-check to make sure I didn't miss a recently released/updated one.
mcgeezer/Antiriad answered first (Propack / Cranker) and I mentioned Shrinkler and maybe one or two more while using those two in the video.
Results: (kinda anticipated)
- Shrinkler: Smallest, ~2K/s decrunch speed
- Propack: Medium-good compression, ~18K/s speed
- Cranker: Medium compression, ~60K/s speed
