I received this coin today and I certainly can see why they decided to not produce the BU version. There would not be much difference between a proof and BU of this one.
I look forward to Commems review as I'm sure it will be very detailed and complete but in the meantime, I'll note a couple of observances. Firstly, I really like the details of the design. It has a classic feel and balance. The second sailing ship is a nice touch as is the note of Heart's Content, NF on the map.
The other thing that seems different to me is the Queen's effigy. It looks to have less frosting especially on her face which appears more detailed than other recent mint coins.
Overall, I'm pleased with this one and look forward to comments from others who have it in hand.
