Why British paper warships look more buildable

Were British paper warships more realistic than German and Soviet designs?

They often look more realistic because Britain possessed the industry to build them, forcing design studies to become conservative and reduce risk as procurement approached.

German and Soviet paper designs could depend on obtaining enough time, money, technical information and industrial capacity. Britain's greater ability to build its proposals made the pressures of actual construction more immediate. As a design approached production, speculative features could give way to more conservative choices. Scharnhorst's triple 11-inch guns provide the example of reducing risk. A capital ship that performed below expectations would still be preferable to an expensive ship that proved unusable.
