I guess any Achievement Hunter videos are good :) King Venus did a good couple videos too I got a small video on my channel which turned out really good :)
I already watch a lot of Hermitcraft btw.
Watch one or two YouTubers from the HermitCraft Server (Grian, Mumbo-jumbo, Iskall85, VintageBeef, Tin-Foil-Chef etc). All of them put out high quality stuff and some of their creations are kinda insane
If you looking for some funny stuff i highly recommend lazarbeams minecraft series
Hermitcraft series are fun! So are Dream and Georgenotfound challenge videos.
