2016 tbMBP 13" base vs 2015 MacBook Pro 15" base

[rsg1010]

Comparing the 2016 tbMBP 13" base to the 2015 MacBook Pro 15" base:

How does the Intel Iris Graphics 550 compare the Intel Iris Pro 5200 for general UI tasks, lagginess, etc?

Overall Speed and Performance comparing both laptops (Usage: office productivity, web browsing with 10 taps, light photo and video work and occasional bootcamp use)

Would SSD Performance be the same in real world usage between both?

Would the 15" get updates and smooth performance for minimum 4-5 years?

I'm also considering that if I upgrade the 13" MacBook Pro (2016) to 16gb ram it essentially makes the computers at the same price point so wondering what advantages/disadvantages each computer would have over one another.

Wondering who else has been contemplating between both and what your reasons are for choosing one over the other.

Returned my nTB 8GB/256. USB C peripherals like hubs and cables seem to be postponed until summer at least. Will rock the 2015 base 15" for the next two years. Let the early adopters be nice children and wait for Christmas.

A big difference between the 2015 15-inch and the 2016 13-inch is going to be the processor. For lighter work, the real-world difference is usually less pronounced. For more intensive work, it can be night and day. The 6 year old quad core in my 2011 MBP runs circles around most new dual cores. The area I personally notice the biggest difference here is when running multiple operating systems at once, where it is so pronounced it is almost comical. I personally feel the quad core laptops will maintain technical relevancy longer than dual core laptops.

The SSD on both are fast, but the 2016 is notably faster (IIRC the 2016 can read/write something insane like 2.5 GB/s.) If you are exporting massive video files, this could be pronounced (as could the ability to take advantage of the USB 3.1 spec.) For the work I do, it's usually not.
