I have, it's worth getting, it definitely scratches the same 'must ... optimise ... better ...' itches.

It's early access but very playable and feature complete, but it does feel less polished than factorio (obviously can't compare to an 8 year development effort!)

Satisfactory is another great play for fans of the genre.

Both games are 3D, and both use the additional dimension well. You can play them fine just like factorio (I did the first runthrough) and treat 3D as eye candy, but you'll do better if you 'cut with the grain' and learn how to build 3D factories.
