Anyone tried 1:1 mentoring/production tuition online?

Does anyone have any experience of using a 1:1 music scheme online? I was intrigued, searching around here that there are a fair few posts in favour of it to some degree. I see there are many of them kicking around in various Patreon tiers.

I’d be interested to know, if you used a mentor at any stage…

Did you have calls or was it mostly text based chat?
Did you want tuition (almost akin to a personalised course) or coaching?
What sort of cash did you invest (monthly) in this?

And at the end of it, did that feel like a better step compared to (say) doing a course?
