The ability to search for keywords in different industries, which allows me as well as my team members have access of all relevant information about our competitors without having any contact with them or their employees. Nothing that I dislike at this moment since it has been very easy using its features like keyword searching among other things that make up one's research work easier than before when working alone. It helps us do better by knowing what we are missing out there so far from time being able to use more advanced tools such as Google Search API would be great but not sure if they support deep dive duck yet? However even though you can't run your own instance (at least till now) still recommend trying because once used will never regret doing business again!
