If I would compare engines, and one engine turns a specific prop faster than the other engine, that faster spinning engine clearly delivers more power. There are no if's about that.
But when I need fast spool up, fuel puddling and power curve play large roles, which makes four strokesmore desirable.
Because engines are inanimate, they can be quantified very well! An engine is defined by it's measurable characteristics, and exacting choices can be derived from that. There is no magic or feeling involved. Just plain mathematics.
