You might get an argument about that. The card reader on the CDC 6600 was faster than the IBM 2540, and managed to read mangled cards that the 2540 would reject or jam up on. A decade later Documation produced a 2501 compatible unit with similar technology. While the IBM 1403 with a TN train produced crisp text, the maintenance for it got so high that in the eighties we switched to a Documation 2250 that was faster and cheaper than IBM's printers.
