Second Asana. I've been using it for years and it has really improved tremendously over that time. There are definitely still many things missing (most notably for me is the lack of advanced markup in comments/conversations)... but it works very well for cross-functional collaboration and longer-term project management.

I've just started using Asana in the last month, the very first thing I noticed was how incredibly slow the interface is to respond. Dragging things around on a board is particularly painful compared to Trello or Github Projects.

I also find it incredibly annoying that when you add a card to a column, it adds it to the top of the column, rather than the bottom.

However, aside from those two annoyances, it does seems to offer a lot of useful functionality.
