let me tell u the differences: -
1. 930 has a Carl Zeiss 20 MP camera with BSI OIS with PureView, apart from mindblowing apps (like refocus and cinemagraph which are currently nexus nowhere near).
2. no stereo sound for video rec. and only single LED flash in nexus, no dolby for audio enhancement in nexus.
3. no FM radio in nexus
4. AMOLED display verses IPS LCD in Nexus.
5. better performing battery
6. both have 2GB RAM, but for as i said earlier, 2GB for WP is too much more than required.
Pros for Nexus
1. java support
2. comparatively larger app base
3. light in weight
if u compare nexus 6, u may get a similar performing phone for 930 (i even doubt that). but then again question arise of the comparable price.
