All depends on what you're using it for. We use 7zip all the time at work and it is invaluable and I often see better compression rates depending on the data involved. I just zipped up an Eclipse workspace .zip using 7zip = 27mb .7zip using 7zip = 6.5mb We have a VPN to a customer over a dedicated ADSL link (max 300k upload) and daily we are transferring new builds / files. Which would you prefer? Edit: you can also create a self-extracting 7zip as an executable as well with a very minimal payload (couple of 100k)
