i think they’re both great family rides, but overall they’re just okay.
looking away from the theming, Kansas Twister is a fun little coaster, but i do wish it maybe ran a bit faster on the return trip and was a bit longer.
FOTWW has a fun layout and the drop + first turn are decently intense for a family coaster, but it’s way too short and it’s a capacity nightmare. not being able to do up your own seatbelt, while the gates also don’t open until the station is completely empty, while it’s also only able to run one train makes every dispatch around 4 minutes, that’s only around 300 people an hour. so by the time you actually make it through the boiling hot queue line and experience the fun, but 30 second ride, you’re left with a sour taste in your mouth.
for the hardware itself, FOTWW is my preferred option, but for how they are at the park, the experience of Kansas Twister is better imo, but they’re both just way too short. part of me thinks they should’ve gone for either a singular coaster like a big bear mountain / fire chaser express style of ride or a Vekoma STC & family boomerang combo.
