> Blue Moon HLS is considerably less complex than Starship HLS
That's the one thing in your comment I disagree with. Starship-based HLS has basically one base vehicle, modified into three variants (tanker, depot, and the lander itself). Refueling is done in LEO.
Blue Origin's HLS has three completely unique vehicles with no commonality (New Glenn, Transporter, and the lander), and refuels in multiple orbits, one of which is NRHO, which is likely to be far more challenging. And they're doing it with hydrogen.
Blue Origin's Mk1 cargo lander is simpler; their HLS architecture is not.

JMHO.
