Best way to define route in Symfony?

Question

symfony

Here I see 4 ways only in the docks. The question is for those who have been writing on the symphony for a long time and have dealt with large projects.
Which one is the most flexible and which one will be easier to maintain when the routes are over 500?

Answer 1

Yes, which one you like better and use it.
I personally prefer to use yaml.

Answer 2

Of course, it’s a matter of taste, but as for me, if there are a lot of routes, then in YAML it’s visually more convenient to look at them
