Looking at the three most recent Soyuz variants:

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%.

Falcon 9 is more reliable than Soyuz.
