No, but Danes and Swedes were more easily disposable on sea than Ottomans in 18th century in my opinion. Russians were having bigger means in north than in south. Also Baltic straits are not so narrow as Bospor.
P. S. No city on Black sea cost could ever surpass Istanbul, since Istanbul controlled straits. City on Black sea coast would always stay hostage to power that held straits. It was inevitable that most dominant city of the region would be built on the straits.
