7-zip gives me 5 options for the compression method to zip files with:
- Deflate
- Deflate64
- LZMA
- BZip2
- PPMd
On my Windows 8 machine, the built-in Windows Explorer utility appears to handle LZMA with no problem can list the files in an LZMA-compressed file with no problem…but not actually read them. I know Deflate is the most compatible, but for some files I'm attempting to distribute, the maximum setting results in a file that's 2x larger than the LZMA-compressed file. However, because the people I'm distributing it to have whatever OS, I need a widely-supported format.
What compression methods to the native zip utilities on Windows 7, 8, and Mac OS X support?

If your primary goal is compatibility with all/most OSs and unzipping tools, then Deflate is your best choice.
