I imagine UH-60 and variants will continue to serve (who knows, maybe with new airframes) along side the MV-75 for quite a while, in a similar way to how UH-1s continued to be in use well after UH-60s were deployed in large numbers. This Congressional Research Service summary of the FLRAA/MV-75 program states that the Army has plans to continue ordering UH-60s (on the order of 255 between 2027 and 2031) - https://www.congress.gov/crs-product/IF12771
The key requirements that drive MV-75's downsides (size, complexity, cost) is the Army wants to play game in the Pacific. The UH-60 is deeply limited there.
For example, the MV-75's range should let it go (one-way) from Guam to the Philippines, straight from Okinawa to Taiwan (no need to island hop) - potentially as a two way mission. Same as Philippines to Taiwan.
The "comparability" is that the MV-75 and UH-60 can be delivery ~14 troops into an order magnitude similar size clearing.
