I like how easy it was set up within our organization; we used other tools before but this one had some really great features (like being able connect directly from GitHub) so no learning curve at all! There's nothing in particular i dislike about reqtest - everything seems very intuitive once you get past your first few questions/tasks when setting things out initially :) We're currently using their Test Automation module primarily as its pretty powerful & can do nearly anything else would need via scripting or API calls.
