What is the best Minecraft youtuber?

Depends on your taste if you like RP Style series' then go for DanTDM or Stampy, there are also the group that do How to Minecraft every so often.

I watch Skeppy, he likes to play well. I want to kill him when I play it.

I am watching Frost
I think is the best youtuber in Russia

I do not like all the YouTube people who make a video about maincraft,

Aypierre and Aurelien_Sama ! The best youtubeurs in France !

If we're talking about youtubers that ONLY upload minecraft content its https://www.youtube.com/user/PrestonPlayz

That's your opinion. There's no way in Hell that everyone can agree that x or y is best.

Antvenom he makes educational and interesting videos (in my opinion.) Never heard of the guy you are talking about in the original post though.
