Global coverage so covers more than just English and much more actionable than answer the public &
Requires a paid account, also slow to process data
The topic research done for "car insurance" in Australia (desktop) showed some nice ideas... brand terms... roadside assistance, ctp insurance, accidental damage....
The ability to hide unsuitable terms or drill down into these terms for more detail is also great. I love the headlines and questions that are generated based on that term along with the related terms similar to answer the public. If you are really stuck they also offer some long tail related searches that are perfect to dive deeper into a particular topic.
In card mode you get suggestion heads, questions and related searches for that particular query which is great when you are looking for very high level terms.
I also tested the tool in dutch as most tools struggle outside of English and found it managed to produce a fair number of great topic suggestions. Well done folks!
