I've climbed up both trails. The good news is that there are handrails on the parts of the trail that are steep and exposed. Bad news is that they have become so well documented that they are filled up with crowds.
I believe that the Half Dome trail is now on a lottery system ... at least during the peak times of the year.
"Bad news is that they have become so well documented that they are filled up with crowds."
Can't get away from crowds... even at the top of Mt Everest.
