Have a read of the rust release notes [0] to see why the ? operator actually improves code readability.

It's not obvious from the simple example given the original article, but as the release notes mention it makes things like the following:

try!(try!(try!(foo()).bar()).baz())

much more readable:

foo()?.bar()?.baz()?

If the main concern is readability of code, the latter wins hand down.
