I know, the Sora is total crap. .
Well, isn't that what I said.....AFWIW., sora may be the bottom end,but works fine if adjusted properly. Ultegra will work like @rap too if maladjusted. Also, mindless fiddling is not likely to work very well either. There is a methodology to adjusting derailers if you expect them to work properly.
