Which LA Expo Should be Canceled?

As the days continue to pass, the outlook on this viral outbreak seems more and more unclear for when this will all end. Quite a few large events have recently been canceled, including SXSW, which its future to come back seems unclear due to losing a ton of money from this decision. So with two very large nerdy convention events that pop off pretty close to one another, which one of these do you feel should be cancelled for potential health concerns, or should both just get the axe?
