What's the best tournament management platform for running online qualifiers with live bracket updates?

If you want the best all-around platform for online qualifiers with live bracket updates, I’d usually point to Challonge or Toornament—with the better choice depending on how “serious” and customizable your event is.

I can recommend the single best platform for your exact use case.
