For features and performance, the 6s would have to be the best. However, for build quality and durability, my personal preference is the 5s.

I still don't have an iPad mini or Pro... not good considering my Apple stuff. :( I guess I *don't* have to buy it just for the sake of having it.
 
Better is always highly subjective regardless of topic. Define exactly what you mean when you use the word and don't assume it to be a universal matter. For me it's the 6s due to screen size and specs. YMMV depending on your specific criteria.

Can I like all three for different reasons?
Sure -- again, you define the criteria for yourself.

Opiniongate.
Gategate.
 
the bluetooth has been improved over the two models. The earphone jacks remain the same.
Overall, I can see why the OP votes the 4S as being the best of the best.
 
6S is the best, bigger screen, better resolution, battery life, exellent camera, incredible slow motion mode (take a look at the videos), it's thinner, etc, etc
 
Jobs did not introduce the 4S. He passed away the day after the keynote and did not officiate the keynote, nor did he attend it. If you look at replays of the keynote, you'll see an empty "Reserved" seat in some shots. It's been speculated that this seat was reserved for Steve, either symbolically or in case he had the strength to attend.

The last iPhone Steve Jobs presented was the iPhone 4.

I am interested to see what they do for the iPhone 7. I'm hoping for something totally new. I consider the iPhone 6 to be somewhat derivative of the iPhone 5, not a total rethinking as the iPhone 4 was.
I now own the 4 and it's a little slow. :(
 
Obviously the 6S Plus is technically the best. Which is the best phone for each individual is down to personal opinion.
