Depends on what kind of debts.
I'm an "old" millennial that recently got a raise and cleared all my credit cards after years of having them loaded near the limit. Now I have a positive balance in my account and enough to live for a few months without a salary. It boosted my credit score to average. So that's great!
However, I live in a studio and don't think I can afford to move anywhere much bigger nor buy any kind of property. It will still take me years to save enough for a mortgage.
So I guess it's still nice not to have any debts, but I would also prefer to have paid off a mortgage instead of "only" credit cards.
