Why would that be incorrect? Yes the GS2 has a pretty Samoled plus screen with great contrast and cartoony poppy colors, it's also a benchmark beast, destroying every other phone out there, but does that alone make it THE best phone?
I think not. While Touchwhiz 4 is better than any version that came before it, I like Sense better, Personal preference for sure, but to me Sense looks more polished, more uniform, and more useful. Touchwhiz tries too hard to look like an iPhone and it just looks inconsistent as well. The Sense widgets also look nicer in my opinion than the Samsung ones.
Specs wise the Evo 3d has the obvious 3d screen which adds a lot of extra functionality, and it does have a higher resolution display. And while neither phone has confirmed support for Netflxi streaming, seeing how the Evo 4G already has it, I am sure the 3d will get it as well in short order.
You can't just go out there and declare total victory for one phone without considering all aspects of the phone and also personal preferences among users.
