The Vizards were also using their masks against Starrk, they didn't use them against MDM. They were fodder to Starrk anyway, it took Shunsui's broken abilities and a sneak attack to take him out, I'm not so sure that the Espada have been eclipsed just yet, at least not the top 3 strongest
Stark clearly admits his ceros are not strong enough to beat strong guys like the Vizards. They also tanked several explosions of his wolves and get up, but a single star beam from Base Mask one-shotted Rose.
Renji casually incinerated Mask when he was powered several times over.
