Best quiz plugin

I spent 3 weeks trying all the quiz plugins on the market, including the most expensive ones. And at the end I chose Quiz Maker. It’s the best by far. I don’t need any add-on to create what I want. There is a ton of customization. It is very fast (much faster then Learndash quizes for example). And the support is amazing : they always reply with a helpful answer super fast. Thanks !
