This 100%. When you see what TouchWiz is capable of, not just the aesthetic customizations, but the ability to truly manipulate how you use your phone and the apps within, it's really impressive and makes iOS' "app drawer" style all the more stiff looking.
In TouchWiz, you can resize your home screen grid format, resize apps themselves, split the screen for multi-tasking, "minimizing" apps, turn on privacy mode (of the entire phone, not just a browser or something), engage battery saving modes, customize quick settings.... just to name a few examples. Smart Stay sounds pretty useful, too. Having a back button, also, is a huge functional advantage.
It just feels leaps and bounds ahead.
