I find doing things in unity3d using the new audio interface is this easiest for me. I'll eventually learn wwise and fmod, but with these then you have a layer over that for me to get confused on. For 360 video, I just like a well mixed mono track and I don't worry about ambisonic formats. I think the entire 360video experience is more for quick commercials and marketing over a huge range of devices, so a good mono track that works with things like phones and iPads is important. Apple drives me crazy in the vr space, a couple years back all development was on Apple, but now 90% of my dev in in Windows 10. I do build my stems on protools 12hd with the waves nx virtual mix room plugin on the Mac though ... Just to make sure the stem is solid. But the full mix is done in the middleware(wwise or fmod or unity). I've given up on my safari browser supporting basic vr sound correctly, with unity you don't have to deal with those issues since they package everything up so their is no player.
