Re: Tiki, or WikiSuite?
WikiSuite includes Tiki, and thus offers all Tiki's features.
WikiSuite also provides you access with features Tiki doesn't have. Ex. Tiki can't sync your files. For this, WikiSuite uses Syncthing. Please see list of components (click on each to read up on what they do): http://wikisuite.org/Software-Components
Also:
Tiki can run anywhere PHP can run (just about anywhere, including shared hosting).
WikiSuite requires your own server. This is inexpensive nowadays, compared to a decade ago.
