I really likes the LabRoots platform. It was easy to navigate and felt like being physically present at the conference. I also loved the diversity of the research presented between the plenary sessions, symposia and lightning talks. I also liked that the different talks were available on demand for 2 weeks following the end of the conference; it allowed plenty of time to catch up on missed content.
