I haven't ridden both Vijay, but be aware the Tiger is geared significantly lower than the Sprint - 10%. Therefore the acceleration will be much greater than just the engine specs would have you think. Obviously lower gearing affects top speed, but in general we're talking about 20-30kph off the absolute max so it doesn't have a huge bearing on the real world.
Given the S3 was geared 5% lower than the Sprint, I can say that lower gearing gives a greater rush and didn't affect fuel economy.
Here's a comparison of ratios between the 3 incarnations of the 1050 motor:

It shows front/rear sprocket size, final ratio, variation to the Sprint and the speed in 6th for each bike from 2500-10000 RPM.
