I'd prefer Hyrule. It doesn't seem like leaving Termina was exactly an option, and if the moon crashes for sure with no Link to save you, you're very likely dead (I know if you actually do the math, the idea is that the moon wouldn't destroy all of Termina, but we have to take into consideration that the moon is 'magical' so it's not just about its size and speed). On the other hand, in Hyrule, Ganondorf probably won't kill you for no reason. Anyway, he wants the kingdom he's ruling to have some people in it, I'm sure, otherwise there'd be no point.
