Today at work we had a fire alarm, and we were outside for quite a while waiting for the fire department to show up and give us the "all clear". While standing in the parking lot and suffering through 105°F temperatures, I decided to run a Speedtest run. To my surprise, I was provided the best download results yet: 32.36 Mbps! Holy shiznit, I'm in love with LTE!
If it does come to VZW. Get the SII no question about it - at least over the Bionic.
Is that a personal preference, a la preferring TouchWiz over MotoBlur? Or is there something else that you make you come to your conclusion? The Bionic is reported to be launching with a qHD display (960×540), versus the WVGA (800×480) on the Galaxy S II. Though, I've read reports that the Bionic might launch with a pentile display, which be an instant deal breaker for me. The Super AMOLED screen on my Charge is absolutely gorgeous, and the Galaxy S II will be supporting the same (or similar) display.
On the other hand, lots of people prefer Motorola's sturdier build quality over Samsung's choice of cheap feeling plastics. Both phones will be running dual-core processors, with the Bionic possibly running a 1GHz dual-core Tegra 2 compared to the 1.2 GHz dual-core Hummingbird on the Galaxy S II. Both will be also LTE phones provided the Galaxy SII does come to Verizon. I would think that purchasing one largely boils down to personal preference, and not necessarily higher-end specs on one phone or the other.
I failed to mention that the Galaxy S II has 1GB of RAM versus the 512MB on the Bionic. So, that's +1 for Samsung.
Heavy is good, heavy is reliable. If it doesn't work, you can always hit them with it.
