I don't really know about Funhouse, but between Double Dare and Legends, it's pretty close for me. Loved both of these shows as a kid, Legends of the Hidden Temple especially. My favorite edition of Double Dare was definitely Super Sloppy Double Dare, felt like the best mix of 'raw' and 'produced' show production.
Also loved Wild & Crazy Kids when I was a kid too, but I don't think it holds up quite as well watching as an adult, where I think those other two do. Guts also holds up really well and I enjoyed it a lot as a kid too, but it always fell a bit lower in my rankings of these game shows. And with Guts, I definitely think it improved more over time as it found its footing, similar to Double Dare.
