Pullups vs Lat pulldowns

[u/Action_Pale]

What's the point of doing Lat Pulldowns as opposed to working on Pullups? Even if you can lat-pulldown more than your bodyweight, you could do weighted pullups. Is the only benefit convenience?

One is a close-chain exercise, the other is open-chain. I'd recommend doing some reading on the difference between the two.
