[Is a clean install better than upgrading?](https://askubuntu.com/q/5466/) has been reopened again. This will make it easier to keep it up to date. There's less incentive to keep a canonical question up to date if it's closed, and it's harder to review possible duplicate questions if the logical canonical "duplicate of" question has answers which contain obsolete content or are not up to date.

The objection that it is opinion-based still stands, but it is inherently a toss-up because the answers to this question contain many facts too.
