I've tried so many PM tools in the past, but nothing that really fit with the way I work. Upbase is the closest to perfect as I've found. The layout is clean and navigation easy - this is very important. They also have features like bookmarking different filters and layouts. Some features like that are a little hidden, so make sure to read the help docs. The only thing I would like to see on Upbase is a whiteboard. Specifically, a whiteboard where we could arrange tasks visually.
