While there are many great Youtubers, I personally like Markiplier. His content isn't family friendly but he's selfless and really cares about his fanbase. His charity livestreams have raised thousands of dollars. If I had to pick one not on the list, I would go with Rhett and Link. Their show Good Mythical Morning is family friendly and enjoyed by everyone in my family. They post videos every weekday plus a behind the scenes video every Saturday and I love their 'Will it (food)' episodes.
