You're missing lots of options that have been proposed:
microbitcoin
microbits
micros
mics
µBTC
uBits
crobits
zib
It's not much use as a poll if you've already limited it to your two favorites, including one (renaming "bitcoin") that's nearly impossible to pull off without major confusion and risk of money-losing errors.
we have moved passed the mBTC uBTC argument as moving to those would only be temporary and short term. it appears the consensus is to stay with bitcoin for while longer and then move to 'bits' (100 satoshi) that way the move across is not temporary and wont confuse people.
as for anyone proposing to call 100sats a 'bitcoin' i find this will confuse people. its far easier to separate the two as bitcoin and bits, the same way that people separate
1 from million
ingots from bars
ounces from tonnes
basically i am trying to say that calling a ingot a 'bar of gold' is stupid and confusing.. yes i understand that there are some poor people that want to scream to the heavens "i have a whole bitcoin". but thats just a ridiculous thing to do as those that have multiple real bitcoins (100,000,000 sats) will just laugh at them and correct them that they are still poor.
i prefer bitcoins being 100,000,000 satoshi's and bits being 100 satoshi's.. it just makes sense
