Well, me and my team used to manage all our projects with MS Project but the integration with Jira never worked quite well so I was looking for a different solution and I had a very positive experience with WorkOtter.
Something that really surprised me was the support team, they were amazing and helped us out during the entire transition process which was a great deal as my team was overloaded and could not leave their daily jobs to work exclusively on this software transition.
One other thing that seems simple but was a big deal for us is that WorkOtter send reports to users emails automatically. We have to do that a lot during the day and it saves time.
I am from Brazil and they support English only. I already mailed them with this suggestion but no ETA yet.
