I have been playing Factorio for some time now. I really want to get started playing one of the overhauls. But which one? I find it hard to get a good overview of the different options.
Pyanodon is very very very complicated, but fun in a different way. You might spend 10 hours just automating one recipe. You also probably would want to add some quality of life mods like Far Reach, Early Trains, Jetpack, and of course FNEI so you can look up recipes. Py is less focused on optimal factory designs and more about many different cascading product types.
Pyanodon is intense! I always give up when I get to the point where you have to import/export twenty different items from one production area. I have on idea how you handle logistics for that.
