Focus on one-liners?

I just did my very first open mic yesterday. The set (5 min) was on a single topic, whereas most other people that went up bounced around various topics and crowd work.

At the end of the show the host (who knew it was my first time on stage) told me while I’m still new I should focus on doing rapid fire one-liners. Do people agree with this feedback?

I’m happy to share the recording if anyone is open to giving me feedback. I saw on the community guidelines to hold off on posting my performance for feedback until I’ve done it a few times.
