I have the 1+1 and a Z3 Compact. I much prefer the 1+1 due to the screen size, I thought it would be too big to use as a phone, one handed etc, but it hasn't been an issue. I really appreciate the extra screen real estate from the 1+1. The Z3 Compact has been a great phone in its own right as well, albeit in a much smaller form factor (with many of the same internals of the 1+1). The build quality of the Z3 is outstanding, the screen beautiful and interface (as expected) is extremely zippy, but the best feature about the Z3, as it's a work phone, is the battery. I last charged this on Tuesday morning, this morning (3 days later) it's sitting on 79%, this thing will last longer than a week with light to moderate usage, the 1+1 I get about 3.5 days on a charge with moderate usage, the price you pay for a 5.5" screen (that said, 3.5 days is still pretty damn good, my 920 was lucky to last longer than a day).
