We'll go on a bit of a blogathon today, and will start with some low-hanging fruit. After 67 (of 100) games in the TCEC Season 8 Superfinal between Komodo (9.3x) and Stockfish (021115), Komodo leads by three games. The games have been interesting, but chess at the 3200 level being what it is a whopping 62 games have been drawn, with Komodo having a 4-1 edge in decisive results, including two wins with the black pieces. (Stockfish is doing pretty well so far in game 68 though, so its fans shouldn't give up all hope just yet.)
Update: The title had the result backward. Rest assured, reptophiles, it is Komodo that's in the lead.
