JiraPS is a wonderful module that is great at a lot of things. There several great people that have put a lot of time into it for it to have such good feature coverage. It was designed to be approachable and do a lot of validation for you. JiraPS does not have a good user story around bulk operations with its issue commands and thats what I need from it the most.
It also has a large user base with hundreds of thousands of downloads and is used in a lot of organizations. Every change made to that module at this point needs to pay very close attention to backwards compatibility.
Now there are two modules depending on your use case.
