Well my 2013/2014 Roadster is just about run-in now with 2K on the clock, and since this is my 6th Rocket spanning 05,06,07,09,11, and now late 13 models, I think I can speak with some authority.
Riding position - I like it, even though I am 6' 3" tall, I like the mid mount pegs for spirited riding in the hills but I will put some crash bars and highway pegs on for the longer straight boring sections of highways.
Handle Bars - Far superior, this is the first Rocket that I wont be putting T Bars on as I like the bars as they are.
Gearbox - No comparison, these gearboxes change gear a lot better, smoother than any other Rocket I have owned.
Finish - I love the way Triumph has removed the protective film over the alloy triple clamps and rims, far easier to look after and keep shiny. The new blacked out color scheme I love, and is the reason I ordered one when I saw the skunk color scheme when they were first released to the media.
Power & Torque - Since all my previous Rockets have been De-restricted and worked on to some degree, it is harder to work out the real benefits of the new models de-restrictions have had. It feels a lot smoother and gruntier than a restricted model, and this is the first stock Rocket that I have owned that will power wheelie in 1st, so the de-restrictions have worked.
Overall, I love it.
