The X Edge class ships have a great walking track, but it is not MSC. I prefer Yacht Club to the Suites on X. Their pricing is out of this world, and they have not perfected the "ship within a ship" model the way MSC has. X has tried to add MSC things, like private drop off for Retreat Luggage and an escort onto the ship, but they fell short on that, as they did by putting Lumenae on the side of the ship that is so open and loud it is like being in the MDR. I have read they have fixed some of this on the Ascent. We will be on Ascent, but the suite prices were too high. We don't like the window cabin they call a balcony cabin, so we have a rear veranda.
I know the MSC ships are a bit like a maze, but hey, you just deal with it and enjoy all the amenities that are being offered. Where else can you find a glass floor several floors over a pool?
