mbtc is much better since it is inbetween. 1/1000 is very easy. 100k satoshi is a nice amount and easy to see. 0.1mbtc is $0.80 for example. 10 mbtc is 0.01 btc. Very easy.
Some of the other people here have said satoshi is good for fees and it is. For fees a small demonisation works best. Just like how bytes kb mb gb tb work.
Well there is well over 80 trillion fiat in circulation.
So let`s say .000000000000000000000000000000001 for a coke
No fool, a coke is like 10 thousand satoshi. Quite simple, come live under hyperinflation to see where your value of things in time end (which Dietrich suggested before getting kicked for supporting the "wrong" person).
FYI 10 thousand satoshi is simply 0.00010000 or 0.0001
BTC. Is that 0.1 mBTC? I don't even know, i also refuse to use that.
If you know then why do you ask?
