What server would be the best for streaming

I’ve been considering joining an RP server to start streaming on but I can’t for the life of me figure out which one would be best.

What I’m looking for,

- Fairly serious, good role playing

- Popular on YouTube & Twitch

- Preferably a whitelisted server

My current options,

- EchoRP (definitely leaning towards)

- ProdigyRP (although quite hard to get in to)

- RedlineRP

- 17th Street

- GrandRP (heard that it’s not great)

- PurpleRP

Which of these would be the best? Are there any others that I should look into?
