2 steel processes-various questions

So, I've been doing some researching, and I'd like to know-which steelmaking process, Bessemer or Siemens, was used more commonly worldwide? Which nations used which one? Was either more suited to specific purposes (EG making steel for ship hulks) more than the other, and if so, what were the specialties of each process?

Thank you in advance; I'll probably think of more questions as we go along.

The Siemens process was used to create armor plating for warships. I think it was also used to create the steel used for making heavy guns. The Siemens process is slower so it makes it easier to manufacture steel to very tight specifications.
