I think you'll find the timing chains on the ten weren't keen on the new service intervals! There is a better replacement chain for them though.
RS is ok, but I just couldn't splash that money. They look great from a distance, then you get up close and see the rusting cheap sliding calipers and the fake vents under the lights.
I've driven the RS and was quite impressed with the torque. I hate the dash and the fake carbon print stuff though. I've been out in one in the wet... Let's just say it reminded me why I love my 4wd turbo stuff.
