Best way to get catalysts?

is it speed running regular strikes or legendary nightfalls?

Same question tbh, I’m missing so many and haven’t got one in weeks despite runnings most raids on most characters every reset. Haven’t touched playlist content though so I suspect that’s the problem.

I use this website, it gets regularly updated.
They're in alphabetical order and they tell you where to get and how many kills it'll take to complete catalysts
