I think underestimated Pammukale last time with a little unfair downvote last time. I forgot it gives ammenities too, and it is that factor giving it more value since last patch. It had no value before, so I forgot it even has this bonus
Anyway
Player is dependent on map generator. So you can land in bad terrain with Roraima around, or you can land on geothermal fissure near noountains and get soon similar or better science. You can roll Tsingy nearby, or start in jungle with coffe and crabs on the cost. Yes, all of them make life easier, but are not gamebreakers, because all that can be obtained in ususal way by simplystarting in a good area with correct resources and terrain features (coffe, crabs, amber, reef blah blah) or proximity of city states
What I consider top natural wonder is that of gamebreaking value, gving you bonus, that cannot be obtained early in oher ways, and there is no chance favourable map generator would give similar effect. those wonders will give a value not possible to get any other way.
These are three wonders, and this is my obvious top3 for this elimination thread
Paititi, because its yields are too high to be obtained other way
ZD, bacuse map generator would never give you free trade route capacity and great general (followed by enlightment, mercantilism inspirations, free envoys for quest that otherwise would wait for eras)
Ik-Kyl, +50% to wonders with jungle/foest around is not possible to get by any other means.
I know some of you would start now a story starting with IF making a chain of things that would lead finnaly to having better effect (if you start near TdP you would have a bonus hammers and IF you go for bronze and IF you build a encampment 3 turns faster and IF you run project and if and if and if and between those ifs that fact of population limits dissapear). I don't want any IFs from natural wonder. Top Natural wonder has to give maximum effect with minimum engagemant and conditions and its bonuses are impossible to get other way without complete detour of usual way of playing. Like ZD. It loses value as game progress? Every natural wonder loses. maybe expet Eyja....
For some reason ZD is still undervalued here, but I won't upvote twice in a row.
Instead
Eyjafjallajökull [16] 15+1 Good volcano
Mount Kilimanjaro [9] 12 -3 Bad volcano
I can easily settle terrain where Kilimanjaro spawn without it. Settling terrain where Eyja... spawn is hard without it.
Islandic one is less destructive and fertilizes more in one eruption
