I use classic character models because catacombs models are unbearably ugly to me. The result is that I see a lot of other players who have decked out their characters in weird ways, and I assume it's because they're using catacombs and I just can't see all their bling. It also makes me wonder how stupid my character probably looks to catacombs people.
I'd be curious to see some side by sides of y'all's catacombs-classic models for your characters. I'll post my own tonight when I get home.
(Relatedly, it'd be nice if we could style both models independently. I doubt that's possible for the devs to do, but yeah.)
Edit: A day late, but here ya go:

Cool look.

Ugly as sin look.
