Statcast era is more accurate. Also, the Statcast era hr's were clearly excluded from that list per the list's title.
Of the top ten Statcast Hr's, three have been above 500:
1. Nomar Mazara, Texas Rangers - 505 feet (2019)
On June 21st, 2019, Mazara smashed a 94.7 mile-per-hour fastball from Reynaldo Lopéz in a game against the White Sox- setting the Statcast era record for the longest home run ever.
2 (tie). C.J. Cron, Colorado Rockies - 504 feet (2022)
Three years after Mazara, Cron unloaded a 504-foot rocket against the Diamondbacks on September 9th, 2022. It is the longest measured home run in Coors Field history.
2 (tie). Giancarlo Stanton, Miami Marlins - 504 feet (2016)
Six years prior to Cron, Stanton hit a homer for the same distance against the Rockies, with it being the first 500-foot homer in the Statcast era.
