Which way is more efficient for an anonymous coroutine?

So, I have a game where I use coroutines a lot, creating them many many times. Which way would create the least lag? I'm guessing the top one, but idk exactly, am I right?

local cocreate = coroutine.create
local coresume = coroutine.resume

coresume(cocreate(function() --first way
	while wait() do
		print("Test")
	end
end))

or

coroutine.resume(coroutine.create(function() --second way
	while wait() do
		print("Test")
	end
end))
