TestRail Customer Satisfaction Rating
Gleb Budko, a Software Developer at Autodesk, Inc., would be very likely to recommend TestRail for this reason:
I am the one who did research for a test case management tool for our company. I compared different tools and TestRail was much better compared to the others. TestRail works really fast. It has a clean simple UI. Compared to other similar tools, the UI is really clean.
Most important is that TestRail has a really good workflow and intuitive test case management.
