Zoom works in two ways in Ai – one is based on the pixel density of the display, and other is on actual (physical) size of the element. The setting to control this is in:
Preferences > Display Print Size at 100% Zoom
Above setting ensures what you see at 100% zoom would be the physical size of the art. You can actually put a ruler against the screen and a 1inch rectangle will measure 1in on screen at 100%.
But this may not work right for screen design workflows. Make sure you uncheck this, if actual size zoom is not needed.

I have this issue too. The pixel-grid snapped image looks crisp the moment you turn the Pixel Preview on (Crisp.png). But once you zoom in or zoom out, it becomes a pixel mess (Blurry.png).
The reason for that it seems is the zoom factor. For pixel preview to be crisp, the zoom needs to have some weird fractional value. But the commands zoom in/zoom out jump between nice rounded zoom levels thus turning the pixel preview into an unusable mess.
