Adobe XD, it was great, but compared to the competition, its lacking.

Back when I used it, it was great at incorporating the rest of the Creative Cloud software. Copy pasting from Illustrator was always easy, as well as linking files from Illustrator as the designers could update the file in real time and we see it change. Copy writing team also had an easy time implementing copy while work was being done, so we never had to worry about manually importing in copy. The main use was for website design, specially client sites. We were to map out the entire site and work on the main pages the client's site would require in order to be deployed.
