Please try to answer in these areas:
- For what kind of usage is OpenSolaris more suited than Linux?
- What are the useful OpenSolaris features that Linux lacks?
Personal experiences are welcomed, but please don't start a flame war. Strengths of Linux over OpenSolaris are beyond this topic.
(For Linux, I'm thinking of something like Ubuntu or Fedora, but not RHEL, if that matters.)
(I have used Linux servers for a long time but have never used Solaris, if that matters.)
