First let me say i hope i can be non bias. I own a Galaxy Note 1(phone), and a nexus 10. I got my girlfriend a note 10.1. I also owned a Xoom before replacing with the nexus 10.
They are both great tablets. The Note 10.1 has the s-pen which is awesome. I really don't think a capacitive stylus can come close to it. It also has Samsung's exynos quad core processor so you are not loosing much from the a15 in the nexus 10.
Both are great the biggest thing you loose or gain is screen on the nexus 10, and the s-pen
