I'm not sure about the best but the one match that stands out in my mind, for incidents if nothing else, is a game from 84 or 85 - Argyle 6 Preston 4.
I remember the weather was awful and by the 2nd half it was a mud bath. Argyle came back from 3-1 down to lead 4-3 and then 5-4. I remember Tommy Booth the ex Man City centre-half getting sent off and all the North End players chasing the ref, who then sought refuge behind the photographer's behind the goal. It was a crazy end-to-end match in every respect - even one of the corner flags broke in half after someone slid into it. Shame there was only 4-5 thousand there to see it.
Also I think Tommy English came on and scored from the spot, but I might be wrong there the Pen could have been Tynan.
