Between the Z2, the HTC and the G3, the G3 is definitely the best looks wise. Reading the reviews the downside is that its plastic.To be honest the only other phone than the Lumia that interested me was the LG G3, very decent phone that.
Do not go BB, seriously, I have a few of them in the office and they are absolutely horrible.
Hopefully Lumia creates a Absa app the next 2 months
