What do you prefer to Jira? At a former workplace we used Gitlab, which was a pleasant suite to use. These days we use Atlassian and often find myself incredibly frustrated by their products
- You can break down tasks into subtasks and those subtasks into subtasks themselves, etc
- You can dynamically group task columns by who's working on them, what is their status, what is their goal, etc
- You can arrange what's to be done on an effort-value grid, which helps immensely when choosing what to take on next
I've heard good things about Rally.
Trello was good and simple, back when it wasn't owned by Atlassian (the makers of JIRA).
So far as I know, that's about it.
Does it look good? Nah, not particularly.
