WYR have superhuman mental faculties but be transported to 25,000 BCE or have below average mental faculties and live 25,000 years in the future?

In the first case, you have the ability to perfectly recall everything you have ever learned as well as anything you learn in the future, you can perform extremely complicated mathematics in your head, and are otherwise superhuman in every possible measure of mental capabilities. You are transported to 25,000 BC in your current location. You arrive with underwear, a shirt, pants, shoes (and socks if appropriate) and whatever you can fit in your pockets, and are given approximately 1 hour to prepare.

In the second case, your intellect would remain unchanged, but by the standards of the year 27,000 you would be considered severely mentally disabled. Upon arrival, people are insultingly condescending (even children) and you live out the rest of your days as a research subject, being studied by scientists and put on display in museums and universities across the galaxy.
