So I currently have a iPhone 5. I'm looking to sell it so I can get a new phone. I'm going to probably take a break from iOS. Since I'm getting a cellular iPad Air as a graduation gift I feel I have too many iOS devices already, so I'm looking to retry android. I had a Note 8.0 in the past but Touchwiz made it super slow and I ended up selling it. However I flashed stock Android and liked it better, so I'm looking for an Android that's smooth and non-laggy. I'm looking at the HTC One M8 and the Sony XPERIA Z2. I've never tried an HTC device, so I'm stepping into unknown waters here, but hear great things about it. However for Sony, before my iPhone days I had a Walkman 780i phone and an XPERIA X1, and I really liked them. So I'm considering the two, both have their pros and cons, but not sure what to choose. I want a phone that lasts all day, unlike the iPhone 5, good audio, and of course, as said earlier, needs to be smooth and have no lag.
