There was a succession of interesting engines (I think The King used to win a number of computer tournaments, this is the one Chessmaster used, that wonderful audio-visual program, like Encarta but chess related) and then the big three of Fritz (match against Kramnik), Junior (match against Kasparov) and Shredder. And also HIARCS and later, Rybka (and Crafty, as well, touted as the open source chess engine)
Stockfish has been top dog (fish?) for a while now but there was a notable exception when AlphaZero (which later became Leela? I'm not sure) beat it, but these days of course Stockfish is far and away the best engine (I guess. I don't know how far behind Leela is)
And, yes, human vs computer chess has stopped being interesting for a while. There were some centaur chess (human and computer; humans using computers to analyze) competitions in the 2000s and some interesting things but nowadays of course your phone can handedly beat Magnus Carlsen and others without problems, reliably
