"Holy trinity" is just an historical term for those three brands
It's like the "Ivy League" of colleges. It doesn't mean MIT or Duke or whatever is second rate, just that these are particularly old, elite, and often compared for reasons of pride and historical rivalries. The "holy trinity" of Swiss watches is just that and nothing more.
The term doesn't reflect a running battle to be one of the three "best" in the world. I'm not even sure how you determine the "best" in the world. If it were, weird stuff made in 6-24 pieces per year would probably populate the list with nothing but individual preference to determine the ranking at any given moment. Is MB&F really going to spend more time per watch, offer more customization, or decorate more finely than Aaron Becsei or Ludovic Ballouard? Moser mostly mass-produces watches with a level of decoration you'd expect on mass produced watches from IWC or JLC. Rexhep/Akrivia probably spends far less time per watch than Raul Pages, but he make less than ten watches per year.
Really, brands that excel in some ways fall short in others, so it's hard to compare them. For example, Moser makes nice watches, but Ulysse Nardin and GP unarguably have deeper present and past catalogs of innovations. Even Arnold & Son generally decorates movements better than Moser. Moser is fun because it has an engaging CEO and watches that embody cool mechanisms from outside experts like Andreas Strehler, MHC, and others. The watches tend to be reliable these days and durable enough for daily use. But have you seen what Credor's Micro Artist pieces offer at comparable prices? Or how many original calibers JLC and Zenith have produced in their centuries-long history? Again, there's just no way to rank these holistically. Usually, a brand will have both strengths and weaknesses that don't align symmetrically with others in the business.
Best,
