My partner and I are going to apply from within Canada. Even though I know the timeline in the states is not long, my partner and I just came to a decision that this is the route we would rather go. We like being together more than worrying about a timeline plus I am fairly confident that even if our case was sent to the local CIC office. I doubt ours would take that long considering we live in Newfoundland and we live 15 minutes from the capital. Plus Newfoundland people are super nice so I think I am set for an interview. Lol. And I haven't saw many people at all apply from Newfoundland so I doubt they will be that backlogged. Even if it takes a while, I am fine with it because I know that in the end, most of us will come out with the same result. If it doesn't work out the inland process then we always have the outland to fall back on either way, if you have a good case and put together a strong application then you will still become a PR. I think it takes a lot not to be approved for it. Timelines always vary because everyones life and history is different but I say go with what your heart tells you. It won't stir you wrong. 
Oh and we will be applying Common-Law as well. Either way I wish you the best of luck and ease with your application. I am sure you will do well.
