Different

- Redmine supports many databases while Tiki is MySQL only (and MariaDB which is a drop-in replacement to MySQL)
- Tiki hosting requirements are easier (shared hosting)

- Tiki is the Free/Open Source Web Application with the most built-in features so it has more built-in features than Redmine.
- Tiki has features for which Redmine doesn't even try because it's not needed for their use case. (ex.: Spreadsheet, etc.)
- Redmine has better SCM integration (SVN, CVS, Git, Mercurial, Bazaar and Darcs) while Tiki only has SVN
- Some of the project management features (ex.: Gantt) seem more advanced in Redmine
