I'll take the BM786 thanks.

J-R:
That "simple" argument is objectively bogus and doesn't hold up to scrutiny.  The BM857s has a significant number of shared functions and multiple settings per switch position just like the other models:

BM857s has 9 function switch positions.  4 are shared functions in the strict sense.  7 have multiple settings.
BM859s has 9 function switch positions.  5 are shared functions in the strict sense.  9 have multiple settings.
BM867s has 9 function switch positions.  5 are shared functions in the strict sense.  7 have multiple settings.
BM869s has 10 function switch positions.  7 are shared functions in the strict sense.  10 have multiple settings.
BM786 has 8 function switch positions.  4 are shared functions in the strict sense.  7 have multiple settings.
BM789 has 9 function switch positions.  5 are shared functions in the strict sense.  8 have multiple settings.

Also, the BM857s/BM859s and BM78x have 8 buttons, while the BM867s/BM869s have 6.

Ultimately, due to the mode memory that can't be disabled, all Brymen DMMs can be a pain to use in many cases because you never know what function you'll get when you flick it on, unless your life is so dull that you memorize the last setting or write it down every time you turn it off.

The 121GW with the mode memory hack is a joy by comparison.  The setting I'm using is remember the mode while it's on, but reset to the white-lettered functions after power-off.  Predictable.  Dare I say "simple".

The only thing I really toggle on BM857s is Ohms/continuity, and it's really easy to know when it's in the wrong mode.

No need to even look at the screen, just touch the probes together.

That's a good second choice but it has three functions on a single range (Ohms/continuity/Siemens)...   :P

(size is also similar)

I feel this is a topic that's never been explored. Which meter needs the least button pushes and mode selections in daily use?

Fungus:
Another topic:

What's more useful?

a) A BM869s,
or
b) A BM857s and a $30 Zeeweii oscilloscope?


Edit: I should point out that the Zeeweii has an "auto" mode that scales both horizontal and vertical to match the incoming signal. It's fast at doing it, too. Just probe the DUT and there's the wave on screen complete with measurements, no need to do anything else.

Fluke 117 and certain meters from Hioki (4252, 4256, 4261, 4282) come to mind, if we are not too far off topic.
