Help me decide

[npost59]

I'm sure this has been discussed before, as I have read many post on a ln Explorer ii (1216570) vs Sea Dweller (16600). And there seems to be a 50/50 split on what to get.
However, my collection currently has a 40mm Yachtmaster (126622) slate dial. And a Explorer 1 36mm (114270) black dial.

I am looking for something different and keep going back and forth with what to get. I like the white dial option with the Explorer since it's drastically different from what I currently have. However I had an older Explorer ii 40mm polar and got rid of it for my Yachtmaster. The sea Dweller is black just like my Explorer so I don't know if that gives me any more versatility than I have.

I would like to keep my purchase price under or at 10k.is there another Rolex that should be considered?
Thanks for your help.
