Wait you're not taking synths and world shaper together are you?
Synths don't get the happiness buff from Gaia worlds as the Gaia modifier is "biological_pop_happiness" - which synths arent affected by.

And ecumenopoli pump out +10% more output than Gaias too.

The only real benefit I could imagine getting out of that Synth/Gaia setup is slightly more efficient mines
- As you won't really need normal planets for farms anymore.
- And energy is ludicrously abundant already, so +10% technician EC on a world is nice ... but if you're hitting your stockpile cap ... meh.
IMO it's better to just take mastery of nature on a regular world as +2 mine districts = 4 jobs each receiving additive output benefits (even if they are 10-15% lower than with a gaia world) this will overall lead to more output than with a Gaia in all but the most extreme cases. The same goes for voidborne and mining habitats (though the ROI is less clear-cut there). Honestly worldshaper is one of the best perks you can get lol.
So it doesn't make much sense to me to take those 3 APs (synth ascension and Worldshaper), unless I'm missing something?
Taking world shaper for Gaia planets (I say that like it offers anything else lol) isn't worth it if:
- You synth ascend
- You get Zroni
- You are Gestalt
- You go full slaver / biological ascension (happiness bypassed with lobotomies)
- Go habitat/Ecumenopoli or mega-structure heavy.
Really the only time world shaper / Gaia is worth it (for lack of a better term) is when you go spiritualist as you can make a few Gaia consecrated world without having to find one. And spiritualist/psy ascension is already the weakest of the 3 so... meh.
If terraforming with world-shaper unlocked all primary districts (i.e. hive-world style) that'd make it a great pick. If terraforming also cost "terraforming resources", not just EC, then it's cost reduction would actually be relevant, too.
