I agree that OP perhaps jumped the gun too soon on the return, but I understand his/her frustration with Touchwiz as compared to HTC. I'm coming from a year apiece with the EVO 4G and 3D, and after over a week with the GS3/Touchwiz I can conclude that HTC Sense beats Touchwiz IMO hands down. Some direct comparisons:
I like widgets, and HTC has a lot more variety and functionality in their widgets. In particular, their People and Friendstream widgets are must haves that were not available on the GS3. I downloaded Android Pro widgets, which is an acceptable substitute but not as good.
For some reason, Facebook contact links refuse to work on this phone...only Google contact photos are displayed for most apps (the stock Messags app displays photos, but the stock Contacts doesn't...weird!). This may be an ICS thing, but I'm guessing that it works on the LGE 4TE...I had ICS on my Evo and the contact links worked fine. I'm hoping one of the devs gets this fixed in a custom ROM, it's a near deal breaker...I hate those blank photo squares!
Dialer app for HTC is easier to use. The GS3 app for some reason doesn't let me designate a default action. So if I use a contact widget to call someone, I still have to select the number to dial in the dialer app, even if there's only one number...so 2 clicks to call or text someone from a widget, instead of one using HTC. I may be missing something on the GS3, but I can't see how to set the default action.
Having said all that...I'm still sticking with the Sammy. I've had HTC for two years, and it's time for a change...plus I do like the phone, the screen is gorgeous. I'm sure I will adapt to Touchwiz before long, or replace with a new launcher.
