If panspermia does happen in the universe, I bet that it happens with the sheltering of asteroids and meteors. Life develops on low-gravity planets with turbulent atmosphere -> some cells get into space -> get caught by comets and other objects -> slowly propagate within comet -> comet has an unstable orbit that sends it to another system, where it has an encounter with a habitable planet. An icey comet could provide radiation protection and it could accidentally go through a gravity assist to increase it's speed. I suppose that the best evidence we could collect to prove or disprove panspermia is to see if it's happened between planets/moons/objects within our own solar system.
