This is just an idea that popped into mind.
As someone who uses both mediums a lot, I like to think they would work together rather than fight.

As for character designs, the traditional guy is an older, strong character. A bit rough around the edges and fittingly I made mistakes while colouring. That's how I feel traditional art is like, you make mistakes but you just roll with it and sometimes it works for the better.
The digital guy is much smoother and younger as he is newer.
