This outbreak has officially made it to the top the second-tier for me if you were to try and rank its place all-time. In terms of the sheer number of tornadoes, and the significant number of intense tornadoes, this outbreak is up there with any of the major ones we've had in the past 20-30 years, maybe longer. Numerically, it's even ahead of 11-17-2013 and 4-14-2012 which were the two biggest outbreaks I've followed since I really got into following these set-ups every year
The only thing this outbreak is missing for it to be considered a Super Outbreak is a high number of violent tornadoes. That's the one thing that still sets apart days like the Palm Sunday 1965 outbreak, the 1974 Super Outbreak, and April 27, 2011.
Still, this was an historic outbreak.
