There is probably no uniform answer to this question. It very much depends on the way these chips are implemented. I dought it that someone here would ever have compared them.
The one real answer is to try them all and listen.

Some people prefer the sound of tubes and the parameters of those amps are nowhere near the ones of SS. I think it's just easier to work with LM3875 compared to lm3886, because it has less pins to work with and I like P2P. Sound: you have to decide for yourself. Configuration, schematic, parts, preamps, speakers..... To me, the less parts in the way of the signal the better (combined with a sensible circuit design, of course), because all components have their sonic characteristics, so less time spent on tweaking (less places one can screw-up the signal) and more time for listening to music.

Build them and tell us what you think.

if you stick with power opamps that are 'known' to be good, it's more a matter of choice...
Do you want to match them with your (theoretically speaking) hard-to-drive loudspeakers or do you have a fantastically easy to drive, super high sensitivity horn system?

here's a thread that lists the most used power opamps in commercial products.

It's also based on mute mode. If you need mute mode for your power amp, I suggest you use LM3886, LM4780 and TDA7294 for your amp. For me, LM3875 and OPA549! very good!

Default LM4766

I prefer to use lm4766 because it's easy to buy,and some people say it sounds like a tube amp, I'm interesting with it.
but I wonder ...as a newer type of NS 'overtrue' amp series, why fewer people have uesd it?
