Difference between using bottleneck vs Kue, BeeQueue, BullMQ, Agenda, etc?

[hagginoaks]

So I'm currently using BullMQ, and I'm doing some webcrawling with it, so in an effort to throttle my API requests, I happened upon this module.

I'm curious if I can just swap over to using Bottleneck altogether instead of Bull (or another js based job scheduler)?

My use cases are: web scraping, sending email notifications (new user, forgot pw, etc), and some daily stat reporting.

Cheers
