Egyptian, Mexican and I believe Siamese are one of the strongest of Great People.
Egyptian ones are really strong as there are 3 of them giving large bonuses to building wonders.
Others too have quite interesting effect, i.e. Han ones could boost science with codices and free tech.
Most conquistadors are very good. Many will fill your armies or Columbus basically reveals the entire map.Hmm... I very rarely build great people. Egypt is the exception as it is worth pulling the slot machine wheels in order to get some guaranteed wonders. But all the other civs with great people (before modern) are extremely hit and miss - to the point where I don't think it's usually worth rolling the dice. In modern you are usually beelining so again I rarely build them.
I think making it so you got a choice of, for example, 3 great people when you build one would be a good call!
I find most of my new world shenanigans end up being naval, and columbus is a nice to have rather than a must have. But a lot of that is probably down to playstyle.Most conquistadors are very good. Many will fill your armies or Columbus basically reveals the entire map.
I often find the situation where I have nothing meaningful to build in a city in a second half of the age. That's when those great people become an easy choice.The first one is quite cheap: The cost of a Tier 1 Infantry. That is pretty much always worth it. But it does downhill from there. The second one probably at least breaks even. But then you really should think about, whether you really want a third or a fourth one.

A lot of them are meh.
I like the French Archangel of Death, the bonus is not huge but just like renaming the unit
