Is there an idiom / proprietary eponym for a common useful thing? More specifically, in a class of objects for sale, if someone were to order the most common one, which is overwhelmingly the most common example used, it would be the ____ of that class of objects.
Use examples (which sound awkward):
- It's the Coca-Cola of battery-powered mousetraps.
- It's the Kleenex of sorting algorithms.
except that I want to replace "Coca-Cola" and "Kleenex" with something that is less awkward-sounding.
The phrase the Cadillac of ____ is common for indicating the most luxurious / highest-quality in a class; I'm looking for a similar word but with connotations of common, useful, reliable, ordinary, dominant.
