Ya, what paraman told is true. Sensation XE has just overclocked processor and Beats Headset.
I have checked Sensation and Galaxy S2 in Reliance Digital and definitely Sensation feels sturdier and classier in hand. But S2's screen is better and so are alround performance, Camera.
And if the screen size doesnt matter to you, I would suggest you to buy Galaxy note. If you are not sure, go to some shops like reliance digital, Univercell or whichever keeps demo models (Not dummy) and check urself how it feels.
If you really like Sensation XE, buy it. Its a good device. Only thing is I am not sure how good its battery is. All HTC phones have bad battery and not so good camera (Galaxy Note and S2 have excellent camera and good Battery backup).
