Soyuz-U had 765 successes in 786 flights. (97.3%)
Soyuz-FG had 69 successes in 70 flights (98.5%)
Soyuz-2 has 160 successes in 166 flights (96.3%)
Falcon 9 has 362 successes in 365 flights. (99.1%). That includes the partial failure of the CRS-1 mission, which successfully delivered CRS-1 to the space station but released secondary payloads into a lower than expected orbit. It does't include the AMOS-6 fire, which would bring Falcon 9 down 98.9%.
Interestingly none of those numbers is enough to give a significant difference between failure rates in a chi-squared test with p < 0.05 - not even if you pool all the Soyuz variants. Though they do all hit p < 0.10.
Thanks for running the numbers, which I think prove that it's impossible to say that Soyuz is more reliable than Falcon, even if you count AMOS-1 (which feels like it should be counted) and CRS-1 (which I don't).

Falcon 9 is more reliable than Soyuz.
