I'd guess the cost of insurance will be about the same for either one and will be one of the most expensive bikes for you to insure. How much insurance costs is highly variable on a number of factors, like your age, marital status, driving record, where you live, how many miles you plan on racking up, how much coverage you want as well as the model of bike.
Both of these bikes are considered to be more of a GT bike than a pure sport bike. They are more comfortable and not as razor sharp as the race-replicas like the GSXR1000, ZX-10R, R-1, etc. If you want a bike for going as fast thru the twisties as you can or for a track day tool, neither one of these is the best choice. If you want a bike for riding all-day at a good clip or want to take up drag racing or top speed contests, then these two are for you. From what I've read of the numbers, I'd pick the one I liked the looks of the best.
