This is a really helpful chart as I'm trying to choose a card. What I'm struggling with is the meaning of the issues.
MPU-401 slowdown/pauses seems to be on every card so I shouldn't be choosing based on that. However it is fairly concerning that it happens since my intention would be to use the card for sound and for MIDI output. Given that it's on every card though I expect my solution would be to get a card and if it turns out to be insufferable get an additional card for MIDI output.
It seems very important to have an OPL3 since not every game will do MT32 etc, so only OPL3 cards suit me.
The hanging note bug I think I've heard before and it's not the end of the world.
I don't know what the Wavetable is. My vague memory has me guessing it's the ability to use MIDI softfonts and that's what the AWE etc ended up with?
Self noise is obviously best avoided if possible by confirming somehow if there's a CT1703 on there.
So digesting all of that leaves me with a bit of filtering to do.
Something I don't understand though is - what is PnP?
