Another plus for Ace 2 : Its will get a Jelly Bean Upgrade officially from Samsung, As far as Xperia U it will always be stuck with ICS (Which too is reported to have lags after upgrade from GingerBread)
Ace 2 will get Jelly Bean!!!
Buy Galaxy Ace 2 rather than the xperia u. Why? Well, here are the reasons: 1.Bigger screen size 2.A micro SD slot. 3.More RAM 4.Near field Communication NFC chip 5.Great Battery - Lasts you all day 6. Samsung's Touchwiz is so much better than sony's Timescape UI 7.Better Bluetooth 8.Slimmer than xperia u And now, let's take a look at what xperia u really beats the ace 2 at: 1.Design: No competition here. xperia U has the upper hand in here. It's one of the most coolest i've ever seen.  2.Display: Ditto. Xperia U is better cause of high pixel density, altough it isn't a much of a difference, but oh well. 3.Sensor: Xperia U. 10/10 4.I think it'll get ICS sooner than Ace 2. And it ends here, the xperia U advantage. I missed the processing power you said? Ah, but it's not a biggie. ace 2 has more RAM, less MHz and xperia u has less ram, more MHz. So, it's quite even, if you ask me. (P.S: The root for ace 2 is already out, and after you root it, u can overclock it to almost GHz without over heating it, which is , believe me super awesome!!) SO, this concludes my comparison, folks. And there you go: The galaxy ace 2 has the double of reasons to suceed than xperia u. And hey, xperia u is a an awesome phone too. So, if you want design with all the sensors and better screen quality go for xperia U, or if you want a faster device with nfc and better bluetooth and other various advanced functions, go for the ace 2!! Thanks for reading and hope my comment helped you all.
