I dont have that much experience with more modern bikes although just rode a brand new 2006 model CB400SB in Japan and was amazed at the acceleration and smoothness so Im guessing a bigger sports bike is more of this and better.
That being said Ive driven my CB750K4 on some of the best motorcycle roads in the world -we are talking the Alps (Swiss/Italian/German/Austrian) where on one particular pass there were 36 hairpin turns within a mile!!! (or close to that) and there were more passes and corners every day, or on Rt 1 California between Mendocino and San Francisco where you can ride for 125 miles all on tight twisty roads, or Angels Pass (outside of LA), or Devils Highway, Mexico, or over countless mountain passes crossing from Reno, NV to Eureka, CA, or on the German Autobahns where you can sit at (an indicated) 100mph++ for as long as you are outside a town. The point is in all these cases my stock K4 (unfaired) handled very good for a 30+ year old bike. Yes cruising at 100mph+ is a scary thing but handling was fine on my bike at this speed- no speed or front wheel wobble (ever!). Cornering is also ok and in my opinion as long as you have good chain, good tires and good front and rear suspension (progressive front springs and stock back for me) - and Im basing this as tested on 36 hairpin loops!!! :-D
Sure Ill agree the bike is big and heavy but since Im 6`4 with long arms I dont have a height issue or problems throwing it around. I like the real-feel driving it gives. Of course if I could afford a modern sports bike I wouldnt say no either

....but so far the CB750 has done the job quite well.

P.S. And starts fine on cold mornings as well :-) And can drive through torrential rain, through snow, high winds, park on beaches, down unpaved forest roads, ride on some of the worlds worst roads (Mexico -Aculpulco -Oxaca) and still survive!! Try all this on a modern bike!!
