Ask HN: Multisite or plugins for a multi-lang WP setup?

The site will be small, only 4-7 pages. Three languages so 21 pages at most if you count the different versions.

What's the state of the multi-lang solutions for Wordpres as of now? I found some extensive plugins for this but some seemed to recommend making the whole setup a multisite WP installation.

What's the best approach, and why? Or do you know any pros or cons for this or that?

The URL structure will be

.com/en/ .com/ee/ .com/fi/

Thank you.
