I've owned several literbikes. For overall competency in a sportbike, they're hard to beat. They're fast, relatively nimble, and exceptionally well-suited to both street and track riding. For track days I actually switched from an 06 10R to my 14R, then promptly bought an 09 10R. The 14R is the best streetbike I've ever owned, but it's too easy to find its limits when riding at the track. You really can't go wrong with a 1000 as a multi-use machine.
What is your budget? The 08+ CBR1000RR, while it has some hiccups, is an exceptionally capable bike. The modest power is offset by the great handling. As long as you make sure you're not buying one of the notorious oil burners, they're also reliable as hell. If you can afford it, however, I would steer you towards the 15+ S1000RR or the new 10R. Both are top of their class in every category.
In keeping with the gratuitous bike porn theme:
