OK that is fine I want list anything. I will just say the S4 is much faster and has a better 1080p screen. I would say either way you go iOS or android you will see great improvement in design over the last.
What I am trying to point out is that while the S3 may not look that much different than the S4 at least it is a new design. Samsung brings new designs each year. My problem with Apple is the S model is simply a spec bump.

Oh because Apple is late to the LTE party we can call that a huge leap. Also that screen upgrade was just stupid. It makes the iPhone 5 look weird. They should have made it wider. Those don't seem to me like very good upgrades.
The S3 to the S4 added a much better screen a wider and longer screen. Faster processor. To me it was a much bigger increase.
And no going to from 3.5 to 4 inch screen and adding LTE is not that big of a deal.
Making the screen wider would not let it stay at 16:9, which is used by all other phones too.
And i would say those are pretty big deals. LTE is crazy fast, like 3G is to 2G, and the bigger screen helps, although personally i wanted bigger, it is too small for my taste.
The S4's biggest leap IMO is the screen. Because of pentile, the more the pixels, the better it will get. LCDs look pretty good on 640p or 720p already, 1080 is just further sharpness. For a pentile AMOLED, more pixels means the sub pixels are now effectively at 720p meaning better text clarity (big deal for me) and less artifacts.
Samsung already has had LTE long ago, and the processor improvement happens to all phones. The bigger battery is welcome too though, means standby will be much better, so will the call time, and screen times will hopefully improve.
And as i stated earlier a couple of posts above, those buttons at the bottom are finally centered, something that pissed me off quite bit on my S3.
I think Apple is more suited to bring "one huge addition" each year, be it a much better camera (4S), or amazing processor and LTE (5), or something else. This is because Samsung already put everything on their first 2-3 generations and can only add so much, while Apple is adding it one at a time and that sort of generates more excitement for next upgrade.
It is just a matter of preference for which model is better. I don't even care for the progression, i will happily switch to whichever device in current gen is better for me, as i also tend to mostly use cross platform services to lessen the hurt from switching around. I am a big believer in hardware makers being just makers and allowing cross platform services from third party developers (or the maker itself), because i hate being locked in.
But so far the thread just seems to be the age old Samsung Vs. Apple battle again with both sides trying to validate their hero.
