We present a Monte Carlo study of the d=3 gauge glass and the XY spin glass models in the vortex representation. We investigate the critical behavior of these models by a scaling analysis of the linear resistivity and current-voltage characteristics, both in the limits of zero and strong screening of the vortex interactions. Without screening, both models show a glass transition at a finite temperature and, within the numerical accuracy, exhibit the {ital same} critical exponents: z{approx}3.1 and {nu}=1.3{plus_minus}0.3. With strong screening, the finite-temperature glass transition is destroyed in both cases and the same exponent {nu}=1.05{plus_minus}0.1 is found at the resulting zero-temperature transition. {copyright} {ital 1997} {ital The American Physical Society}
