If you only include LOC/LOM cases (or ones that would be), then STS does not vary from the Delta II and Tsyklon-2. Atlas II only had about 60 launches, so not enough to compare.
The plain old Ariane 1 / 2 / 3 / 4 flew 144 times, of which 116 were Ariane 4.
Of the 144, seven failed, but five of these failures were traced to the third, cryogenic stage (ESA had hard times with the HM-7).
So the lower composite only failed two times over 144 flights.
Of the two failures, one in 1980 was pogo during a test flight, it was solved, and never happened again.
The other was a human mistake: Flight 36, February 24, 1990. A worker forgot a piece of cloth in a Viking coolant tube.
So the failure rate sounds very much like the shuttle. The bitter irony is that the old Arianes were never considered man-rated, and neither was the Viking.
Ariane 5 and the Vulcain were supposed to be man-rated, but when one looks at Ariane 5 early history (1996 - 2004) it is not exactly re-assuring. Ariane 5 beginnings were rather catastrophic.
Looking at Ariane history makes me think that man-rating is a rather subjective notion.
