Start a new account or use my current one?

Hey, I’m about to start a new channel and was wondering if I should just create a new channel under my current account or should I add another account that’s specifically for the new videos. Is there any benefit to doing it this way? Or should I just keep it all under the same account?

I have YouTube premium tied to my current account, not sure if that makes a difference. Is there any benefit to uploading videos with an account that has premium vs one without?

Any help is appreciated, cheers!
