From what I've seen in the reviews here at Android Central, the SGSIII looks to have everything done very well. It features a newer updated version of Samsung Touchwiz UI. Touchwiz is Samsung's version of a UI, HTC has Sense, Moto has Blur.. etc.. Last but not least is the Nexus line (Galaxy Nexus) which is Pure Google experience, meaning no bloatware, no manufacture UI, just pure Android.
This is all a personal choice as to what you like to see in a UI. They all basically offer the same, just the way its presented and designed to be used and integrated into the device/OS.
Aside from what you probably have already seen in reviews you have watched I'm guessing as many others are that once the SGSIII hits stateside you will see some slight changes to it from its overseas counterparts. Most noted is the opinion of the Home key button and what processor will it be using. Carriers may also want to put their own little spin on things too... Sprint is famous for making a device "special" and stand out from its sister variants on other US carriers, hence see the Epic 4g (physical keyboard) and the HTC EVO 4g LTE which has some changes over its sister devices the HTC One on AT & T and T Mobile.
You have noticeably been doing your homework so keep up the studying and choose wisely. After all once you get past that 14 day return window your married to whatever you choose for the next 2 years.
