And to be fair, I read the comparison between Z1 compact and ip5s from this site - androidpit.
It certainly seems to favor more on ip5s.
1) they stated ip5s beat z1 compact in every tests, only shown one speedtest result which can be very subjective depending on network.
2) No tests conducted, they claimed ip5s' 1500 mah battery to be comparable to z1c 2300 mah battery.
3) they claimed z1c produced crappy pictures, with only few pictures to back up their claims. While other reviews have better pictures to show.
4) they claimed ip5s to be smooth and z1c to be laggy. Most other reviews found the s800 chip in z1c to be blazing fast.
5) they claimed z1 to be very smooth and they have major lag issues with z1c, both having same processor.
What are the odds of day and night difference between same processor?
To believe or not, is up to you.
