I've worked with three people that summited Everest.
Never met anyone that completed the Pac Trail.
I'd rather do the PCT. It honestly seems more impressive.
I think regular people can hike the PCT as long as they are in reasonably good health, and are determined enough.
I hiked the Pacific Crest Trail a few years ago.
I think climbing Everest would be an enormous challenge and a big personal accomplishment. Even guided it takes good lungs and stamina and courage.
