Accurate in what sense? The 2 matches answer 2 different questions. What
precisely are you trying to measure? My guess is you want to measure general
playing strength rather than the relative strength between 2 particular engines.
If that is the case, given those choices, this isn't a close call. One game
against each of 1000 different engines is the way to go.

Frankly, this ought to be obvious.
