Going to have to agree with the Maya, they are the only Mesoamericans to have preserved their culture and even today make up to 50% of the population of their former territories. Also the Classic Maya civilization was absolutely huge and left a thousands of buildings and inscriptions that are still being discovered. I've been to both Peten and Yucatan and basically every couple square miles has at least one ruin or minor archeological site like a shell midden or pottery shards
I might say that the highland maya are underrated but I'm biased because my great grandma was K'iche.
