algebra precalculus - Which form is more simplified? $frac{x-2sqrt{xy}-y}{x-y}$ or $1-frac{2sqrt{xy}}{x-y}$

Which of the following is more simplified, for two rational numbers $x$ and $y$?

$$\frac{x-2\sqrt{xy}-y}{x-y} \qquad \text{or} \qquad 1-\frac{2\sqrt{xy}}{x-y}$$

Sorry for the lack of context; not really much context to give...
