Collection consolidation opinions wanted

[Jcm87]

I’m looking to move out of my 3570 Speedmaster and white dial Seamaster Diver 300M (on rubber strap) to consolidate into one watch. Unfortunately neither of these watches get much wrist time anymore and it’s time to get something that will get worn more.

Planning to use both towards a trade for something else.

My watches in my collection staying are 126610LN, and 126713GRNR.

What I’m deciding between are:
Explorer II 216570 black dial (love the polar but more than I want to spend)
OP41 Blue or Green dial
Explorer 1 214270

Leaning towards an OP due to adding color variety to my collection but would love your opinions
