UPX is tighter and faster (when decompressing). All that is needed is to compress the DLLs with UPX and then embed them as resources (a sneaky idea that I may use in my own code!!) My program Maverick is distributed with compressed Zip and Unzip DLLs. Version 1.6p reduces to ~120 KB. There is a downside with using UPX if the DLLs are used simultaneously by multiple apps (or instances of apps) but I don't think that would be an issue for many people.
