Wow, I would have missed a lot if I hadn't read through this list. Cyberduck does indeed look great. Imported my Filezilla bookmarks on startup. Nice!
It's also interesting to have a new contender for the compression app crown brought to my attention. I've gone through ZipGenius, IzArc, and now 7-Zip phases in the past, I've been reasonably happy with each but eventually run into annoyances (in some cases it's just a slow update cycle as has been the case at times with both ZipGenius and Izarc, though both doing better now I think).
Also have to check out Freemake after its recommendation here as well as in the recent video converter thread here on DC.
