[T-Mobile LG G2x] jrwingate6:
As most of you know, I am a very happy G2X owner. I returned 3 only to get a fully working device with not one bug on my forth try. That being said, here is a list I have compiled of my opinions on each device.

1) UI performance: The G2X is more responsive within the UI and rarely ever lags if not at all. The Sensation has a little lag with the settings HTC ships it with. After turning off the animations within the settings, removing the 7 home screens worth of widgets and turning off the animated weather upon unlock, the Sensation becomes more responsive and lag is almost non-existent. That being said. I have to give the edge to the G2X because the UI just feels faster overall.

2) Browser Speed: The G2X has a slight advantage when zooming in and out using pinch to zoom but the Sensation is faster when scrolling up and down. I hated that I couldn't flick my finger and zoom to the bottom of the page on the G2X. I noticed no difference when it came to loading web pages but the Sensation has the edge when it comes to Flash playback which is noticeably smoother than on the G2X. Lastly, the Sensation can fit more of the webpage on the display due to it's resolution so I have to give a slight advantage to the Sensation.

3) Game Play: Games play smooth on both devices but I loved the Tegra games that aren't readily available on the Sensation. The non-Tegra games I play on a regular basis (Home Run Battle, Angry Birds and Dungeon Defenders) all run great on either device and I cannot notice a difference between the two when it comes to frame rate. I have to give the slight edge to the G2X due to it having the great looking Tegra games.

4) Display: Coming from the Vibrant, the G2X display did not WOW me. Don't get me wrong. It's a good display (as long as you have minimal bleeding) but it's nothing special. The Sensation's display appears more vivid and sharper while noticeably displaying text more clear due to it's higher resolution panel. Both displays are equal when viewing in direct sunlight but neither one is very good in my opinion. I have to give this category to the Sensation due to a higher rez, larger display and a sharper colors.

5) Build Quality: Both devices feel very solid in the hand and appear to weigh about the same when in my hand. I love the rubbery feel on the G2X back plate as hit helps with grip and just feels great on the hand. In my opinion the back plate on the Sensation isn't as good looking nor does it feel as good. However, the Sensation feels better in your hand due to it's round edges. Both devices have a nice curve to the glass as well so I am giving them a tie in this category.

6) Speaker Quality: Both devices lack in this category due to the volume being to low when playing media. Voice calls sound good on either device but they sound a little hallow/tinny on the Sensation if that makes any sense. People on the other end said I sounded fine on both devices. In the end, someone needs to create a fix for the external speaker volume on both devices. The G2X gets the slight edge for sounding better during voice calls.

7) UI looks: This mainly comes down to preference and I like using both the Sense overlay and vanilla Android but lets face it. Most of us always throw a launcher on top of our UI skins no matter what it is. Sense obviously adds more flash to the UI and the new version has some pretty cool features like the new lock screen. I know there is always widget locker but it doesn't look any where near as good and sometimes it doesn't always remove your stock lock screen. Obviously vanilla seems to be faster and is more responsive so this is a category I am not going to name a winner in since it really comes down to personal preference.

8) Camera: Both of them take good still shots but the Sensation's shots look more crisp and records 1080p video much better. Videos appear to be smoother on top of looking better. The dual flash on the Sensation puts out a litltle more light which can be good and bad by lighting up the night club shots better but also washing out the photos a little more. I never liked flashes on phones anyway. Both of them have good camera apps but the Sensation gets the pick here due to video and still shots looking better.

9) Battery: Unlike some people who have a G2X, I was one of the lucky few to have a good battery and could easily get about 10-14 hours on moderate use. That being said, I get 15-18 hours on moderate use with the Sensation so this category obviously goes to the Sensation.

10) Storage and RAM: HTC really needs to start putting more app storage on there devices. It's 2011 and there still only adding 1gb of app storage. The Sensation has more RAM and even though it's running Sense, it shows a little more available memory on a fresh boot which is 263mb and on the G2X it is 249mb. This category gets a tie.

I have one bug on my Sensation and that is the WiFi death grip with holding it in landscape. I am starting to think these company's just don't care when putting there devices on the market. How hard is it to hold the phone in landscape and check for signal degradation?

I hope this helps you make the decision of whether you want to check out the Sensation or stay with the G2X. Haven't made my mind up yet though. I like them both!!!
