On wrestling vs judo in a gi match it depends, at low levels wrestlers do very good because at low levels there is little grip fighting and footwork, they play like if it was early 1900s judo. When they actually fight someone who fights grips and moves, its ugly seeing how wrestlers lose.
I once saw a mundialist wrestler lose in 5 seconds in a judo match against a former wrestler who trained judo with a high caliber coach for 3 months basically match started, he got grips pulled forward did uchimata, wrestler defended so it combined uchimata with kouchi and he fell.
Basically get on grip and start moving, they fall alone.
When it comes to wrestling, obviously the wrestler its going to be the superior man, however the judoka will most likely have the superior TDD in any sport. This may change with new rules though.
Its a lot like gi and no-gi, sure a no-gi man will be better than gi in a no gi match, but the gi man will probably be able to escape and defend easily.
