6k stars, definitely more popular, if less stars means more popular. Obviously more front-end developers love sass! The evidence has spoken.
That said, don't be so quick to just what's popular just by the relative size of the numbers. I'd also check which had a headstart and by what margin.
A 3 year project with 12k stars for example is not necessarily more popular NOW than a 1 year project with 6k stars.
That's why I advocated for several metrics.
