OPEN SUSE:
# Pros: Comprehensive and intuitive configuration tool; large repository of software packages, excellent web site infrastructure and printed documentation

DEBIAN:
# Pros: Very stable; remarkable quality control; includes over 20,000 software packages; supports more processor architectures than any other Linux distribution
# Cons: Conservative - due to its support for many processor architectures, newest technologies are not always included; slow release cycle (one stable release every 1 - 3 years); discussions on developer mailing lists and blogs can be uncultured at times

# Available editions: Installation CD/DVD and live CD images for 11 processor architectures, including all 32-bit and 64-bit processors from Intel, AMD, Power and others

# Pros: Beginner-friendly, especially the commercial edition; excellent central configuration utility; very good out-of-the-box support for dozens of languages; installable live CD
# Cons: Lacks a comprehensive marketing strategy to compete with other major distributions, non-existent Mandriva books show lack of "mindshare" among publishing houses

# Available editions: Freely downloadable Mandriva "Free" installation media for 32-bit (i586) and 64-bit (x86_64) processors; freely downloadable Mandriva "One" installable live media for 32-bit (i586) processors; commercial Mandriva PowerPack edition for 32-bit (i586) and 64-bit (x86_64) processors; also high-end "Corporate" solutions for desktops and servers, all with long-term support options
