It depends on your needs, your strategy, resources and amount of materials you gather. I bought Metropolis theme (at your level) 'cause Uranium Carrier wagon required this theme. But keep in mind that level 95 unlocks Bulky U-235.

Orient and Rio themes give you nothing useful. Don't waste resources for items (themes/decorations/buildings) that you don't need.
