I like that it is easy to use through console or API call as well! It has been very helpful in scaling up my side projects by using its ability of handling multiple jobs at once which helps me reduce time taken from development cycle compared with other tools available out there sucha cronjobs etc!! Nothing much but i have heard some feedback regarding memory usage so make sure you set proper values if needed.
Also check their roadmap before choosing one because things can change anytime without prior notice. ! We are solving our issues related job scheduling & execution/scheduling via queues especially when we need batch operations done simultaneously rather than doing them single-bysingle (which takes too long).
