I've always held opinion that ideal base for our day life computation is 12. It's close enough to 10, so most things would work just as well (like you just need to remember 2 more digits), but it's actually divisible by 3, 4, 6 which is a lot more useful than 5, compared to 10-base.

"The standard among mathematicians for writing larger bases is to extend the Arabic numerals using the Latin alphabet, so ten is written with the letter A and eleven is written with the letter B. But actually doing it that way makes ten and eleven look like they're too separate from the rest of the digits so you can use an inverted two for ten and an inverted three for eleven. But those don't display in most fonts so you can approximate them with the letters T and E which also happen to be the first letters of the English words ten and eleven. But actually as long as we're okay for using the Latin alphabet characters for these digits then we might as well use X for ten like in Roman numerals. But actually now we're back to having them look too different from the other ten digits so how about instead we use the Greek letters Chi and Epsilon but actually if we're using Greek letters then there's no association between the X looking letter and the number ten, so maybe you can write ten with the Greek letter delta instead.

And all you really need to learn is those 'two new digits' and you're ready to use dozenal."

- Jan Misali in his comedy video on why base 6 is a better way to count than base 12 or base 10 https://www.youtube.com/watch?v=qID2B4MK7Y0 (which is a pisstake and ends up making the point that Base 10 isn't so bad).

("in dozenal, a seventh is written as 0.186X35 recurring because it's equal to one gross eight dozen ten great gross ten gross three dozen five eleven gross eleven dozen eleven great gross eleven dozen eleventh's").

Ideally you learn with what you are both with. It’s easy to have base 10 as you have ten fingers. If we only had 8 fingers we could have ended up with octal

Yeah, metric is cool and all, you can divide by ten and multiply by ten. But even better would be a hexadecimal system so that you could halve, third and quarter it. Plus it's n^2 so it's a perfect square \s
