There are definitely amazing points in both proposals. Either way it goes C4L is going to be awesome in 2016. 
Everyone has a different motivation on voting, and think we should keep that in mind. Two years running on the west coast might be more than some can afford. Some may have personal reasons for preferring LA (or can't afford to travel east). Other people may feel super strongly about the Philly beer selection. Or have personal ties to the locations that may be used in LA. 
On the subject of single vs multi-track, I'd say that I would have *loved* a break from the way-over-my-head-and-super-technical single track just for an hour or 2. But that doesn't mean it *should* be that way - I think it could vary from year to year based on proposals. There's no reason not to have a single-track year followed my a hybrid followed by a single-track year. That's one of the beauties of C4L.
