Despite the fact that Samsung has improved upon and cleaned up TouchWiz over its many iterations, it still leaves much to be desired. The biggest complaint is the hit in performance caused by TouchWiz. This is primarily due to weak memory management. According to the latest intel from various sources, that might change in the near future.
Supposedly, Google might actually team-up directly with Samsung in order to optimize TouchWiz. Here's a quote with a few more details,
The reason behind this alleged collaboration seems to be rather clear: TouchWiz UI is by far the most popular variation of Android worldwide and can be found on many an Android device worldwide, which means that the Average Joe and Plain Jane associate Android with Samsung's TouchWiz skin. Thus, having a better-performing and optimized TouchWiz will be help Android get an even better image, in theory at least.
What do you folks think of this if true? Is this a bit of favoritism on the part of Google, or simply good Android community building?
