Cache has a slightly Windows tilt, but that's changing fast. For example, Cache Studio IDE works in Windows, not Linux or Mac. Cache Studio will eventually be replaced with InterSystems Atelier IDE (based on Eclipse). Doc and community support is still slightly Windows oriented but have plenty of info about Linux based Cache.
Linux is a great stable platform for running Cache, either on top of Red Hat (Centos), Ubuntu (Debian) OS or other variations.
I use a Mac running VMware Windows or Centos emulations for testing, developing Cache applications. Then put the production Cache application on a Windows or Linux server, Virtual Private Server or cloud server.
If I have a choice I typically go with Linux. But if you have more experience in Windows, stick with Windows. I don't think you're missing much in Cache running on Windows.
