I've been following the Switch emulation scene in the last couple of weeks. There are currently two emulators in development: Yuzu and Ryujinx. From what I've read both teams are keeping it fair and competitive, without being hostile towards one or the other. Competition between software developers is healthy, as long as everyone involved remains objective and people don't actively try to take sides and say one is consistently better than the other, or wish one of them dominates and the other fails.
From what I can see so far, Ryujinx on average in some cases is slower than Yuzu, but seems to be much more accurate. Here is a comparison between the two using the same games, the first is homebrew and the second is a commercial game.
