It is nice to have some competition and so thank you to the developer, but I see no reason to use this compared to qBittorrent, Transmission, aria2, etc.
Ish. The main advantage of newer clients were simplicity and nimbleness: Azureus/Vuze was a bit heavy on memory, at a time when this mattered more than today. After the Vuze renaming, it also went down a dark ad-filled path that did it no favours, to be honest. So a lot of people moved away.
