Default Razr HD to Note 3?

Hey everyone, I am seriously considering switching from my razr HD to a note 3, just wondering though, whats the big differences with touchwiz? I am used to motorola's near stock OS but want the pen and other features along with better specs of the note. I am planning on buying the unlocked version and getting a ATT sim from strait talk and using it that way.

Just want to have some advice going towards samsung as my last experience with the galaxy prevail was poor but that was a budget phone.
