Both about the same distance, eastridge slightly shorter if i recall, but more technical, so takes longer to do. Hopton is not technical at all, but very flowey, rides really nicely, eastridge is older and more rough and rooty, much steeper, but very very good.
All I can say is when I have a day off work and stay local I try to do both, rather than 2 or 3 laps of one. They are quite different experiences. Whatever you choose, it will be good, enjoy 🙂
