@nicholsonc_electric @Agrizz thank you to hear about your experiences. On par with mine. Exp Builder is worse than WAB. Definitely way slower for users, and doesn't help with user adoption.
ESRI Support told me to reduce the amount of layers in my map. First off why when WAB works, and secondly i only have about 20 layers in there and it still performs poorly.
Keep posting your experiences so ESRI development teams hear us and make a change. This software is too expensive to accept poor experiences.
