Both of those show hex first, and decimal as an additional feature.

In the first place, many people have pointed out to you that Unicode
*is* laid out best in hexadecimal. (Another example: umop apisdn ?!
are ¿¡, which are ?! with one high bit set.) But in the second place,
"what the majority does" actually IS a strong argument. It's called
consistency. Why is "\r" a carriage return? Wouldn't it be more
logical to use "\c" for that? Except that EVERYONE uses \r for it. And
the one time in my life that I found "\123" to mean "{" rather than
"S", it was a great frustration for me:
http://rosuav.blogspot.com.au/2012/12/i-want-my-octal.html
And that's the choice between decimal and *octal*, which is a far less
well known base than hex is. I would still prefer octal, because it's
consistent.
So because of consistency, Python needs to support "\u0303" to mean
COMBINING TILDE, and any competing notation has to be in addition to
that. Can you justify the confusion of sometimes working with hex and
sometimes decimal? It's a pretty high bar to attain. You have to show
that decimal isn't just marginally better than hex; you have to show
that there are situations where the value of decimal character
literals is so great that it's worth forcing everyone to learn two
systems. And I'm not convinced you've even hit the first point.
