My experience with a TKO-1 is pretty similar to what everyone else has said. I think it's just characteristic of this design. The T-5 in my six cylinder Mustang is actually worse. Of course it has lots of miles and the previous owner buggered the synchros with an incorrect clutch. The 1-2 shift is definitely the worst, everything else is OK, but no doubt about it a 833 [ or a Muncie ] with a properly adjusted clutch and Hurst linkage will out shift one every time. I have seen one guy from New England powershift one, beats me how he did it.
