I mostly use Stockfish to analyze positions. Recently, I added Leela as an additional engine for analysis. I figured that both of these very strong chess engines would mostly agree when calculating the best move and the position evaluation. I was surprised! They frequently disagree on both fronts. In fact, the best move of one engine often doesn't even rank in the top three of the other engine's calculations. I also noticed that Stockfish evaluations are usually more extreme than Leela's. For instance, even when they agree on the best move, Stockfish might say that white has a +1.50 advantage whereas Leela might evaluate white's advantage at +0.40. Also, Stockfish seems to evaluate much deeper and faster than Leela. Stockfish gets to a depth of 25 within seconds where it might take Leela 10 minutes to get to that depth - at least, on my computer. Finally, I noticed that in complex positions, Stockfish will often find some esoteric (non-human) move that only works in a "computer line" whereas Leela usually finds a strong, human-like move that makes the position easier to play.
