Should i get Iphone 6s 64GB or Iphone 6s plus 16GB?

So I saw that the Iphone 6S plus 16GB is the same price as the Iphone 6S 64GB… I'm wondering should I get the bigger phone and just deal with the short storage headaches because I really love that the Iphone 6s plus has a longer lasting battery and optical image stabilization but on the other hand… I use up a lot of space… 16GB would be used up in a week for me. So i'm thinking I should get the 64GB 6s which would have plenty of space but sadly the battery doesn't last as long as the plus and it doesn't have optical image stabilization… I want to know is optical image stabilization worth it? Or will i still be happy without optical image stablilization and a phone with plenty of space?

I would definitely get 6s with 64 gb of space.
