Default Is this phone worth it over the Nexus 5?

It is not really that more expensive than the Nexus 5 and tbh I'm getting sick of all these giant phones and want something smaller.

1. Do they have that stupid screen protector thing on that previous phones had? My problem is when you took it off previous Xperia phones, there was no anti finger print layer on the glass.

2. The camera sensor is 1/2.3 which apart from some of the Nokia's is the largest sensor out there, is the camera good or is Sony's Software crap?

3. Is it good overall?
