What to choose for a team wiki - MediaWiki / GoogleSites / DokuWiki?

Question

Startups

Good day! Faced with the choice of an engine for Wiki.
Initially planned MediaWiki
Googling in the bourgeoisie, it turned out that wikis on GoogleSites are also popular ... the
reason is not clear, except that you do not need to install, load hosting ...
BUT! It turned out that large companies also make wikis on them
- but why? ... there is something beneficial for them in this.
- which is exactly what I didn't understand.
Recently learned about DokuWiki ... interested in its ease. I dare to assume that the "problem" is that MediaWiki is apparently loading a server / heavy ...
Or maybe everything is in Redmine? - I heard there is a wiki =) - or for documentation separately / for development separately?
I will be glad to all advice! Thank you very much in advance!
The wiki is for internal documentation of the team. Hosting is virtual, with several projects of different load. I can install the wiki myself. The software has not been tested yet.

Answer 1

the external wiki is convenient because you don’t need to install anything and support
dokuwikis is very limited, you can’t fix it yourself in places, for example, it doesn’t support long urls in Russian.
what difference does it make to you how the wiki server loads, if you enter it only three times a day and apparently you don’t have 100,000 people in the team, any wiki on a small team of up to 100 people will fly.
If you use redmine for tasks, then it is logical to keep the wiki there as well if its functionality is enough and publicity is not needed.
Inside I use redmine and I have a wiki in the same place.
In one project, I keep it in git and use the wiki from git
In another project, we left the redmine wiki because publicity was needed, we chose dokuwiki as a whole, everything is not so bad, but there are slippery places, well, it stores everything in files.
In one project, we use media wikis, to be honest, quite a powerful thing, but such shitty code and shitty usability in terms of settings, in general, it was quite difficult to get used to, really software from the nineties.

Answer 2

Absolutely no difference.
There is also atlassian confluence
There is, after all, a built-in wiki repository in each github / bitbucket project
Feel for what the soul lies more, up to the interface they are all + - the same.
