Thanks for the heads up I'll move over there to ask again.
I think I would go with Jah Keved, I'd be extremely interested in studying the local flora and I think that country has lots of gardens. But going to the Reshi Ilse to see some great shells would be my next choice.
I think it's a toss up between Nalthis and Scadrial currently, but I'm inclined to change my answer to this question regularly.
