There are many differences. The main one is in the fact that mathrm{xyz} behaves like an ordinary letter, while operatorname{xyz} behaves like function names such as sin. Here's an illustration
$sin x + sin(x+y) + asin z$
$mathrm{sin} x + mathrm{sin}(x+y) + amathrm{sin}z$
where it's clear that the second line is wrongly typeset. Even if your "operator" requires parentheses after it, it should be operatorname, as the third summand shows, where a thin space separates the coefficient from the operator.
Another subtle difference is in how some characters are interpreted in mathrm and in operatorname. Suppose you have an operator to be called "pre-norm", with a hyphen. Here's the example
$operatorname{pre-norm}(mathbf{v})$
$mathrm{pre-norm}(mathbf{v})$
and now it's clear what is to be used. Indeed operatorname (and the same holds for macros defined with DeclareMathOperator) treats in a special way punctuation symbols; mathrm, instead, treats them as math symbols.
