Should I get the 64GB or 128 GB iPhone 6s?

Well I have been saving up my money to get myself a new phone, and I now face the question on which amount of storage space I should get. I know I will have a lot of Apps on my phone, and pictures too. I was going to settle for gold 128GB in order to have enough space, since they were out of stock in Rose Gold 128 GB. However I do not mind settling. The price of each doesn't matter, I was just looking for some opinions.

128GB.

You can never have too much storage space.
