Disappointed with Facetime video quality. Software issue?

Hi,
My fiancee is away and we were facetiming when she noted that the video quality looked much better when I was using my iPhone 6 compared to my 2014 13'' rMBP. So i decided to test it out at home and called my iPhone from my mac, and yes the video quality of the iPhone is MUCH higher. I can see that the data stream is around 40-80kb/s coming from the rMBP and 220kb/s coming from the iPhone. Both are connected to the same wifi network. I tried Skype and the rMBP looked great and sent out at 200kb/s, so I know it's possible for the camera to do better. I just don't get why the quality is lower when using Facetime and why the iPhone is able to do it at such a higher quality?

I'm on El Capitan latest beta build but restored to Yosemite to test it out and had same results.

I just Facetimed with my fiancee again. iPhone 6 to iPhone 6, incoming and outgoing data was 230kb/s. I called her back on my rMBP and my outgoing video stream was 25kb/s, her incoming stream was still 230kb/s. This is same wifi network. I then Facetime'd with my sister, she has a 2015 rMBP. Incoming (from her) it was going at 10kb/s, while my outgoing was at 80-90kb/s. I then called on my iPhone 6 and her stream was still awful at 10kb/s and mine was going at 230kb/s. Very weird and inconsistent.
