Well, if you're looking for accuracy then it's clearly the stronger chess player of the two, which nowadays would be the computer.
If you're looking to improve doing your own analysis is better, maybe with a blunder check from the engine at the very end to see if you missed something obvious.
Hello, i have question about analysis. What is more accurate. Game report, which show 'best move', "excelent move" etc..
or own analysis with lines?
