Limited P&S Options - Advice?

[ergalthema]

I have some rewards points on a credit card that I want to use for a point and shoot to take backpacking. Here are the 3 options I have narrowed it down to:
Canon Powershot A3300
Sony Cyber-Shot DSC-W530
Canon PowerShot A1300
Olympus VR-320

I know these are all relatively crappy. I have been using my Galaxy Nexus for pictures the last 2 years. The quality has been good enough for me, but I don't like draining my phone battery on hikes. The A1300 has a viewfinder. I honestly don't know if I would use it.

If you think the Olympus is not much worse than the A3300, then I could get the Olympus and have some leftover points. The A3300 uses all my points.

Any info would be very appreciated!
