RR vs F4i
Totally depends on what you're going to use the bike for. The F4i would be a better "daily driver" for commuting, short distance touring, or for riding with a passenger. The RR would be the more sharply focused weapon for track-day use or aggressive corner carving.
In terms of statistics, there's surprisingly little difference between them- The RR weighs 4 lbs less than the F4i and makes about 10 more rear wheel horsepower. There's only .14 of a second difference in their quarter-mile times 10.71 vs 10.57 in favor of the RR. To the average street rider, this small of a difference in performance is so small as to not even be noticeable. Naturally, the RR costs a bit more- $8999 MSRP vs $8499 for the F4i.
I have noticed that there are dealers who have quite a few non-current model year F4i's in stock and are willing to make big deals on them. In fact, I have a friend who just picked up a brand-new 2004 F4i a few months ago for $6499. A real steal. If you can find a leftover 2005 for a price like that, it might be an important factor in your decision making.
