MSC do a status match. Before we did our cruise in 2019 I think the matched Elite and plus to Diamomd level but that had changed to gold level, the one below black, when we cruised. I doesn’t give much at whatever level you are at.
What is more important is that you get 5% discount if you are a Voyager club member even if you have not cruised with them before so you have to join that before you book the first cruise although we did get the discount added after the booking. Here is a link to the benefits.
