CQRS versus Event Sourcing: when should you pick one over the other?

hey ppl, ive been thinkin bout cqrs and event sourcin lately, esp for syss that need high read perf and a clear audit trail. weve all seen how they can solve certain probs, but the complexity can also be a killer. when have u found one to be a clear winner over the other? are there specific scenarios where ud lean towards cqrs without event sourcin, or vice versa? lookin fwd to hearin ur experiences
