I disagree. In both cases, the scareactors were trying real hard, but with Chucky, the house itself was incredibly cheap, unscary, and had a lot of decisions that actively hurt the experience of a haunt like the constant use of TV screens with overly long video clips to tell the nonexistant story.
Triplets is just a less than stellar execution of a middling concept. Nothing about it screams "worst house ever" other than the overall fan backlash it recieved before the event began imo. The sets are large and well built, if confused within it's own lore and lacking a ton of impact. It's got some decent execution of scares like with the Dog mirror fake-out or the Hobo changing between the street corner and him yelling for help. The Triplets are unique and easy to tell apart from another. I think there are a few other picks for worst house, at least since I've been going in 2016.
Chucky also had some elements that were cool, but the lack of intensity from the puppets, reliance on boring plain-clothes victim scares, and literal barebones sets (don't worry guys, the sets look bad "ironically"
) just keep that one locked at the bottom, at least personally.
FWIW, totally cool to disagree on this, it's all subjective. I've just seen this sentiment a lot and wanted to get my two thoughts in on it.
