Unless an expansion slot for you is a deal breaker and maybe having a front facing camera, I would go with the Nexus 7. The specs are much better.
The Samsung Galaxy Tab 2 7.0 is the correct name/model. At the time I purchased my Tab 2, it came with the keyboard dock and usb adapter. Using a keyboard is a big concern for me when not traveling.
