Yes, without question MD is the better program. I think you can argue Castle does less with more resources (# of students, weight facilities, program $, etc.) than any of the upper echelon SIAC teams. It's a head scratcher IMO.
What Mike Goebel has done at MD is amazing. Prior to him being HC, MD had success, but nothing like what they've had in the 20+ since he's been in charge.
Nick Hart was the final piece of the puzzle. A lot of GS people had worked for years to build a program starting at the younger ages. So while he deserves credit, so do a lot of people who had already been working for years before he arrived.
