You are welcome :) Lets examine something better than ANENG. Or at least seemingly better.

It is 0.02% meter, Brymen style: at two ranges 0.2%, worse for other 3 ranges: 0.3%, 0.4% and 0.15% for 500-1000 VDC.
BM869S has 0.3% +20d on 500.00 mV range. For case mentioned this means 0.5 mV error - 0.5%. Surprisingly it is BEST AC range. 500 VAC range has 0.5% + 40d. At best 45-300 Hz case.
Brymen is 0.1% better than Aneng AN870 in this scenario (quite realistic as sub 1 V AC measurements are not so rare)

Choosing the meter based on the headline spec doesn't tell you which one is more accurate for a specific case. And if that doesn't mean anything, then what's the point of the whole discussion?

If you work in a restaurant kitchen from freezer to pizza oven, you better use an AN8008.
It gives more stable readings over the temperature range than a BM869s says joe smith.

If you need the meter for a particular task, like adjusting a trimmer so the voltage between two test points reads 9 V +/- 0.05% with 99% confidence, then yes, it makes a difference if a meter is +/- 0.02% or +/- 0.07% in that range. But another person might me measuring 900V all day. This means the question which of the meters offers the best accuracy might have a different answer for those two people.

Yes, but that's precisely what's cherry picking and distracting is. You can quote millions different scenarios, and some meters will be better suited than others, but I wrote what I need, and that is "cheapest 0.02%" multimeter, so I can sleep calm knowing my AA battery is 1.456V and not some lousy 1.455V. I thought maybe I missed something cheap, but unfortunately such thing does not exist. I guess market is too small :)
Obviously it's SOP in here for some to bring FLUKEs every time, although topic clearly states "cheapest", but I guess that's nice for entertainment .
