We’ve played Swansea 14 times since 1999. We only played them 5 times between 1999 and 2014.

Bristol on the other hand we’ve played 38 times and almost consistently every year.

For any fans ~30 and under then it’s arguable that Bristol have been or bigger rivals in their lifetime. Coupled with the “Welsh togetherness” feeling the national team has helped develop in the last decade I can see why people would consider England’s Bristol a bigger rival.

I’m in that age bracket and personally would consider Swansea our bigger rivals, but it’s close.
