The ball and socket are a better design. Not sure what headers you’re going with but some come with those.
My vote is here too. Ball socket fixed my leaking collector issue I was fighting for a few years.V band clamps like turbochargers use. Cut off your old collector and weld in v bands.
Not sure of this exact product but this is they type I'm suggesting.

If not those, ball and socket are next.
