I have the Galazy S now and don't have the problems you describe. The new III has bigger screen, still has "swipe" which I really like and other advantages. I'll see if I can find the side by side comparison. The new touch screen on the i-phone has lots of reported issues. The company that makes them for Apple just not got them fixed, that's one of the reasons that they "sold out" so fast, there just weren't enough to keep up with expected sales.
"The iPhone 5 did slightly better with download speeds while the Galaxy S3 enjoyed a bigger margin on upload speeds. Keep in mind that your results may vary depending on your location, the strength of a carrier's network at a given the time, and the number of people using it around you." That quote is from C-net.
