Stenzek who created the duckstation emulator moved over to PCSX2 and the updates from him and others have made that emulator really impressive in my humble opinion. It just seems a bit odd to make a comparison like this. Is there something i'm missing as to why you would compare either?

That sounds interesting, and I've enjoyed reading the deep dives into dolphin emulation. Could you share a link to these?

Its basically changelog notes with each update to the emulator ( usually daily ) and has been very active in recent years. You can also find a wealth of information and upates of various computer and console emulators on reddit r/emulation and that'll have what i think you are looking for.

I'd agree with you a few years ago, but PCSX2 has made leaps and bounds since then. It's quite good now, maybe one of the best.

PCSX2 can run Burnout 3 though. What else do you need?

But this is seriously impressive. Modern Vintage Gamer has done some nice YouTube videos on it.
