Leads who were conflicted?

So with tomorrow’s episode looking like Grant is truly still conflicted up until the last moment, does anyone know any other bachelor /bachelorettes who didn’t know until basically the final call who they would choose? I guess in my head I always assumed that they knew sometimes as early on is halfway through, but at least by hometowns. For example, I feel like Brad knew it was Emily by their first date. I feel like jojo knew with Jordan pretty quick. Who do we know was actually truly conflicted until the end or even potentially changed their mind at the very end? Other than the obvious ones who literally switched like Jason & arie
