Is 128 gbs overkill for an iPhone?

I'm planning on buying the iPhone 6s without a contract (full price) the difference from 32 to 128 is $130. Is this overkill or will I end up regretting not getting it? I literally had no social life during March break so I can dish out the extra cash… It's just. Should I?

Well it's really up to you. If you put a lot of videos on your phone and takes pictures and vids with your phone camera then I would probably recommend it.

I think you would regret anything under 32gb but that is more than enough for most people, unless you want your entire music and podcast collection on your phone.
I personally would get the 128gb if I could afford that and the Apple Care accident plan since that is how much extra I paid to get the 64gb instead of the 16gb when I bought the iPhone 6 for my wife. I would also buy the SIM-free if paying full price. Admittedly only one of four in my household chooses iPhone over Android.
