Ok, well consider this. Why do you want the push notifications for FB messages?
Me personally, I'm much happier getting them when it's convenient for me, I open Chrome, do my thing,and close it when I'm done. I don't need to have my phone beeping at me all day and all night, so I do it when I'm good and ready.
If you "do" need the notifications for whatever reason, can you not set FB to e-mail you a notification of a message? Again, allowing you to simply use Chrome without any additional app?
If that's not an option still, then you might have to go with whatever is going to give you the closest result to your expectations, and live with the bloatware etc. Only you can decide what you are happy to accept.
I do add photo's, but I don't GPS tag them, I don't want to. As for tagging, it can be a bit tempremental, but it does work.
Again, it seems to come down to what compromise you are willing to make, and what you are willing to accept and live with.
