And Floating Superstructures can make huge and large ones fantastic, assuming you can keep your population happy enough.ДЇirst - your racial modifiers. Not relevant for terrforming, but huge specialized gas giants (Frozen, Temperate, Burning) are quite good. However, the endgame favors planets that also have high food generation because the Biofuel Factory is a game changer for production. Larger planets skew towards Ash and Lava. If you have a pop bonus for hot, include Mediterranean. Before that, it's Atoll, then Forest, and Jungle. But we're only talking a few percent difference.ДЄlso, Tundra and Terran are quite good, and huge Barren, Ice, and Arctic remain competitive before Punctured Evolution as well.Дesert is good for production, but usually only after AI Labor. Planet specialization and Punctured Evolution are not enough by themselves to swing the balance to Boreal. Before this though, many planets are competitive, and huge Savanna and Steppes can be best, while Arctic and Desert are also usually good.ДЇor science, Boreal is good, but Ocean is generally best unless you have a pop bonus for cold, such as with the Sophons. Temperate fertile planets are best for Dust, especially so after Adaptive Tax. I just did a spreadsheet analysis on this, see a few posts down. If you want to maximize the science of a 1 hot 3 cold system for example you could terraform the cold planets to boreal ocean and the hot to Terran.Д®dit: As /u/Tychonoir noted ocean worlds actually slightly outperform boreal planets for science pretty much always. On a side note: You can terraform any hot or cold planet to temperate fertile eventually. Boreals Ocean worlds are always the best planets for science, boreals a close second place.Deserts are generally the best planets for production and they only cause a moderate amount of unhappiness.Temperate fertile planets are just generally good really but not outstanding at anything (but food), mostly.And they have happiness penalties between -3 and -8.

They're good at industry and dust, though. Sterile planets have less slots for pops which is always bad. They also have one more pop than other climates (except toxic which is temperate + sterile)ДЇertile planets have more slots for pops which is always good. Temperate planets are best for food and pretty decent everywhere else. Hot planets are best for production but provide no science.Д¬old planets are good for science but provide no production. You can break up planets by climate and fertility and what you get is: Disclaimer: This is meant as a rule of thumb, exceptions exist like races with bonuses towards planet types and so on.
