The highest level character I regularly played was Emrys Kenelm, a human wizard who finally reached 35th level in 2003. I had played the character on and off for years, as he was tied into the campaign setting's history, knew a lot of the other principal characters, and had tons of knowledge.
The challenges at that level included foiling the parts of the servants of Asmodeus (including a band of very powerful wizards), dealing with barbarian hordes and their backers, eldritch horrors older than humanity, and dealing with many other powerful threats. Politics also was a key source of adventures, as sometimes I found my character playing diplomat or trying to uncover various intrigues. So, there were challenges - as well as roleplaying.
However, I think Edena of Neith will testify that Archcleric Hazen of Veluna in the 3rd IR was likely more powerful than Emrys. And I think that Al'Akbar in the short lived 5th IR was indeed more powerful.
