Question [Q] S5 on Stock Android 4.4 video

I'm looking for a video and review of the S5 running on stock android, maybe even some benchmarks if available. I am thinking of upgrading my phone and the S5 is on my shortlist. I can't stand the touch wiz interface from Samsung. I haven't been able to see anyone running the S5 stock. I'm not into themes or cracked apps, I just wan't a vanilla experience. I need to know if the camera is as good running stock 4.4, than it is on the Samsung's rom.

I'm coming from an old iphone 4, so honestly any phone now out is an upgrade lol. I post quite a few pictures to Ebay/Facebook for my business so speed and the camera are my two main concerns. The removable battery and micro SD take care of my other two. Any input would be appriciated as I'm not sure if I should just hold off for the next iPhone in September.
