Guys, what do you think?
Both have IP-XX ratings, which is a non-negotiable for me(praning as it may seem)

Medyo nang alanganin ako sa Z3c because of alleged build quality issues. For the S5, it's larger than the Z3c. i'll be keeping it in my bag most of the time, but i'd like something that will fit my pants pockets.

Support for OS upgrades is also a thing for me, be it official or custom ROMs
