As to answer you, I would go for the MC Geo.
Because I prefer the design of the dial, the complication. And I don't bother too much with the short power reserve, as it is an automatic watch.
I didn't hear that the MC Chrono with the ceramic bezel did have problems.
It is up to you. Maybe should you try them all, before taking any final decision?
Best,
Nicolas

Heck, I could even strap it onto an orangutan, or get some pictures of it with bats or vipers or scorpions...
