After all the bloatware, how much space is on a 64gb iPhone?

Okay, so IIm going to be getting the new iPhone 6s plus with the 64gb, I know that it won't be exactly 64gb due to bloatware and such. So I d like to know approximately how much actual free space will I have and will it be enough for me. I won't have movies and such on my phone. Just pictures, music, and apps. And right now on my android I have about 1,500 pictures, 200 songs, and a lot of relatively small apps. So I just want to know if the left over space will be enough for me.

No bloatware, iOS 9 is now down to 1 GB in size, which is pretty incredible. If you want to compare with samsung "bloatware", the samsung phone out of the box has 8GB already taken, now thats bloatware.
