Blue planet ocean or green SM 300?

Trying to decide between the 43.5mm blue PO and the green sea master. The price on the secondary market is close. I like the bracelet on the PO but the SM has a lower profile and feels a tad bit more comfortable. which one is a better buy?
PO retails for $7100, but can be had under $6k with box and paper like new. Green diver 300 retails for $5900 right now. Grey market prices are around $5500 so there’s not much saving there.

Another vote here for the green seamaster, the dial is just special and wildly dynamic, and it has a lot of character that the planet ocean you have pictured lacks.
