If I have an issue blocking me now, yes it's more efficient to raise that at standup today with the group of people who might be able to help, than wait until next Thursday to discuss it 1:1 with the manager and then wait for the manger to find help for me.

But I'm not a huge fan of standups either, don't get me wrong. They aren't a great use of time, I just think they are better than weekly 1:1s to communicate things like "what I'm working on" or "what's blocking me."
