I may have posted here a while back... Hmmm... Time to bring this back a little bit from like, five days ago with my new opinion-ness.
Right now I really like Good Mythical Morning (Their main channel is OK, though.) and Vsauce.
Why GMM? I rarely like shows about conversation most of the time, but usually it's very interesting. Plus beards and two best friends. |D Why Vsauce? One word: Science. There are some stuff I've asked myself, too, and having it answered in so much detail was great.
I have watched PewDiePie and some other channels though, and thought he can be pretty amusing as well. But right now, I guess I just prefer GMM and Vsauce.
...There's also Danger Dolan too 'cause countdown lists - //shot//
