Water resistant, exactly 5', Jelly Bean, elegant body, 16GB internal + 32GB external, quad core 2GB memory... If true, these are what I actually looking for...

What do you guys expect its battery? How much is your minimum acceptable level?

Z vs Butterfly in battery: 2,330 vs 2,020 (source from GSMArena)

So Z beat B in very department. Next will be on S4. i5S/6 is foreseen to be tiny screen, far lacked behind and not going water resistant.

If S4 no water resistant, then Z will be my next phone. ^^

But if given a choice to choose a waterproof phone and a non-waterproof phone, why choose the later? Unless different pricing.
