@Freak mentioned, that venue gets low wait times right in the middle of the event, but to answer your question and to go into further speculation on the line:
The OG was very popular. I'd say the second most popular of 2011 and 2012 behind The Thing and The Walking Dead respectively.
With that said, it has been 10 whole years since that last maze (WOW, time sure does fly). That's nearly 2-3 new generations of high schoolers who have never been to the event, on top of newcomers in general, on top of the growing popularity of HHN year in and year out, and on top of the people who will specifically come to the event just to check this out since it's such a big urban legend.
With Killer Klownz being done recently, the Universal Monsters never really generating the biggest lines, Halloween being nothing special by this point, the two Blumhouse properties weren't exactly smash hits (Freaky basically flopped even for a Blumhouse title, but at least The Black Phone is doing well), Hotel Deville and Scarecrow may be great but have very low awareness other than possible word of mouth if those mazes are good -- you're basically looking at La Llorona being second most popular again after The Weeknd UNLESS something goes drastically wrong and it's terrible with negative word of mouth steering people away.
