When TouchWiz was introduced, Android OS now looks even friendlier and has an added aesthetic appeal.
Noticeably, its interface is looks and acts like the iOS with just some tweaking specifically for Android functions. Compared to the standard Android presentation, the TouchWiz provides more personality than the latter. There are new bundled app selections varying in usefulness depending on the user's needs.
Every app has a genuine helpful function. It is up to the user to take a look at the other bundled apps to avoid redundancy. The Samsung App Store offers a wide choice of free as well as paid apps.
The most popular Android apps used are the following:
Memo
It is a basic notepad app that functions as a task manager for simple tasks like entering shopping lists, to do lists, short memos, etc. This was missing in the previous default Android setup but can be downloaded for free.
My Diary
This app provides a running journal of events wherein photos and text can be added.
Klies
The Klies Air is designed to assist media and data transfer between a PC and a Samsung device with a TouchWiz function.
Social Hub
This app merges all major social networks in one tool.
So far, Samsung is continuously making the best efforts in dealing with Android issues in basic task management by offering a wide range of apps that may or may not work well for the new Android users who are still struggling to know which one to use first.
Most of the standard apps have been modified with a selection of new widgets added. Directly accessible from the home screen, Daily Briefing and Y! Finance Clock are considered fully functional apps and are very useful to those who sincerely need them. If not, they remain as additional clutter. Generally, TouchWiz continues to give a positive experience to its users.

I still don't understand what makes it different to use than regular Android. You say it is like iOS, but never having used iOS that comparison is no help trying to visualise what you mean.
