STV is a kind of ranked ballot voting system. In the US the term “ranked choice” usually refers to instant runoff voting which is similar to STV but uses a different mechanism for assigning votes so could produce different results. I’m not familiar enough with either to say which is better.
Whichever one is going to get quickest adopted and replace FPTP is better, I think.
I would rather achieve an 80% solution as opposed to failing to achieve the 100% solution because all the energy was spent in squabbling among different better solutions.

STV is for elections with multiple seats, while instant runoff is for a single winner.
