Alright, so lately I've been thinking about getting either a Tarantula (Most likely the Chilean Rose, Mexican Red Knee, or the Chaco Golden Knee) or getting one of those gorgeous Emperor Scorpions. I have been researching the two of them for a bit, but I'm getting a lot of mixed answers.

For example: Many of the Tarantula care sheets say they need humidity, and some say they don't? The same goes for the scorpion.

I really want to know for sure what all they need and the way to properly care for them, I wouldn't want to hurt the spider/scorpion in any way just because of some nitwits misinformation. So with that being said, would anyone be able to point me in the direction of reliable, and correct care sheets for both? And on the opinion side, which would you say would be better for a beginner?

Thank you to anyone who can help me out!
