I haven't used the newer versions of iTunes, but when I DID try it, the problem I had with it was the same problem I have with a lot of electronics components these days, which is they way apple puts the "appearence" of simplicity above ACTUAL simplicity, and "style" above "functionality," which is a hallmark of apple's design approach. There seems to be an attitude these days that "less is always better" when it comes to controls/buttons. Companies are afraid that consumers will be "put off" by a somewhat complex interface (which is true to a certain extent) so they "simplify" the interface to the point that it doesn't "look" complex anymore. The problem is that they take this attitude too far. What both the companies and the consumer don't seem to understand is that this approach can have the OPPOSITE effect -- i.e. it can make using the product even MORE complicated due to the lack of easy access to common functions.
There is a balance that can be achieved in this regard where the interface is still "powerful" without being overly "complicated," and in my opinion MC strikes this balance. iTunes, on the other hand, most definitely does not. It has a very "clean" interface, but it achieves this by sacrificing power and capability, which to me is NOT a good trade off for this type of product. I use MC precisely because it does NOT make these sacrifices -- it offers more power than some may think they need at first, but as you get to know the program, you find that you actually DO want this power, and the extra capabilities of MC are the very reason people prefer it over other applications.
