To clarify: A Fluke meter only has a secondary function on a few of the switch position, a Brymen has secondary and tertiary (even quaternary) functions on a lot of the selections. It
Brymen has the BM857s if you want a simple, "almost-function-per-position" meter to complete with a Fluke 87V.
"Dual display", etc., sounds like a cool feature but if you don't use it very often then it's just display clutter and OP has a Fluke 289 for that.
DC accuracy is on par with a BM869S.
I've had mine for about 8 years and as far as I can tell it's still accurate down the last digit in 50,000 count mode, and 500,000 count mode is pretty close. I don't believe any other Brymen will be superior in that respect.
Thinks I like:
Simplicity of the function selector, simplicity of the display
Really high-contrast/readable display (Flukes fall down a bit here IMHO)
Speed
Lights up any LED in diode mode
Things I don't:
Short backlight time, can't disable the timeout
The stand is maybe a bit small (although I don't use it much thanks to the good display angles)
Looks are a matter of taste but IMHO the Brymen "industrial" meters look better in person than the front-on pics they put on their web site, and their "curvy" meters look worse.
Also, as a business purchase, I would say the BM869s is not an expensive tool. Rather than paying for a warranty, buy three 869's and compare them from time to time to make sure their readings align. If one happens to go wrong, recycle it and buy a replacement.
No need if OP owns Fluke 289's (plural)
