As I'm a bit of a gear geek, I always enjoy the major survey done on PCT thru-hikers and more recently also CDT thru-hikers, by "Halfway Anywhere".
There were 846 hikers that did the PCT survey for 2019, which is quite a decent sized sample to draw wisdom from. The survey participants list their gear, and rate each out of 5, with room for comments, and all that data gets analysed etc. You can click here for full report: https://www.halfwayanywhere.com/trails/ ... uide-2019/
