As for some of the more famous names out there...

Brian (BHB) has a lot of issues that revolve around husbandry and he is a bit of a jerk. Humidity mostly. Is cool that he is fallowing his dream of sharing the animals.
Jay (Prehistoric Pets) does a lot of dangerous things and has bad practices on his videos but has a lot of cool snakes.
Vivids Python has a lot of cool GTPs to see but their prices

The ones I like the best are the lesser known ones that are kids talking about their animals and how to care for the properly and have great setups. I love that the parents took the time to teach them and to see the passion for the animals in their eyes makes me happy. Something else to note here. I have yet to see husbandry issues from the kids that do this. I just do a random search on youtube for kids that keep reptiles and talks about them.
