You can either build cities or build city, upgrade it, build second city ... The former approach is more profitable but at the end you finish with 15 cities and it will take a century to upgrade them all

Ok, counting the prodution output, which way its more profitable?
Because maybe its not worth the effort to upgrade. I mean pound by pound (bulding time/expected prodution) the cities that you can build in the same time that you build metropolis might be more productive....
And what about Spaceport cities? do they upgrade to metropolis?
I don't know but sometimes I feel that the lowly Mineral miner is the best bet.
