Genderless version of "Better man than I"

I (a woman) frequently find myself wanting to reply to a statement with the phrase "You're a better man than I."

If I say this to a man though, it sounds absurd, and to a woman, potentially insulting. Is there a genderless equivalent for this phrase? The obvious choice, "a better person than I", seems to have a quite different connotation.

E.g. someone says to me, "I always eat my vegetables, and run a marathon every Tuesday," to which I reply, "You're a __________________ than I, " or "You're more _____________ than I."

Solution 1:

You're a better mensch than I.

You're a better soul than I.

Alternatively:

You've got more _______ than I, for example

You've got more heart than I.

You've got more commitment than I.

You've got better discipline than I.

Solution 2:

In most cases, people are pretty comfortable accepting "man" as meaning "human". That particular phrase isn't likely to see much use in a formal setting either, so the subtleties of pronoun-based sexism aren't likely to come up through its appropriate use. Otherwise...

You're a better person than I.

Or

You're a better [genderless or appropriate title] than I. (Example: "You're a better vegetarian than I.")

In general conversation, person can stand in for man in almost all cases. It just sounds awkward when used in a title. (Example: Police-Person)

Solution 3:

This is a bit off the beaten path, but I'll try it because I think it would work well. It sidesteps the gender issues of man and the banality of person, while having a humorous aspect. How about creature?

You're a better creature than I.

From Merriam-Webster:

creature: an animal of any type
