I have many favorites, each is based on the rifle that's shooting them, in all my plinking with many different rifles some similarities start to appear but not quite enough to be post worthy. Here goes,
My 2 marlin 60s, best: 525 bulk blazer. One has 1200 through it and the mag tube is Gumming up a bit but still shoots great Worst win 555
1022 TD best 555, worst nothing
1022 shorty dlask best AE 38gr worst 555
Savage fvt best 500 bulk blazer worst anything else.
CZ 452 style best CCI anything, fiocchi std vel ,dynpoint worst 555
Anshutz best higher end stuff, CCI std vel, fiocchi std vel and older win t 22 worst nothing really stands out.
The rest of the 22s seem to shoot everything. I've had horrible luck with anything Remington. 555 and 333 seem to not be quite as good as in the past lately. I find that federal 525s seem to be middle of the road overall. They seem to be cleaner and feed like AE but not quite the same level of accuracy. Federal auto match was junk. The only rifle I have that liked the hotter CCI stuff was the CZ. The savage needed the extractor swapped out with one from an old Lakefield to increase the spring pressure so it would extract the Blazers after about 500 rounds.
