I like the Leman (gee did I suggest that?
) and the UN of the ones you posted. In terms of value, the Leman would prove more interesting to me because Blancpain uses in-house movements while the UN (I believe) use modified ETA ebaches. Not that there's anything wrong with ETA, very robust, but UN doesn't IMHO have the same cache as Blancpain.
As for which BP, I'd go with the ultraslim cuz I like the black dial and the lume on the arabics. Since both your JLC and GO are white dial, the BP with the black dial would prove a big change in look and function.
Geez Al, I wish I had your troubles as far as watches were concerned.
