DT and DB were _clearly_ better than the commercial programs. Does it matter if it was the search or the evaluation or a combination of both? Because if we argue about the evaluation being better or worse, then we digress to arguing about "was their pawn structure eval better or worse?" And from that to "was their weak pawn analysis better or worse?" These are hard to answer. But the overall effect of the search + eval was dramatically better.
