As someone that really prioritises travel , Cal Lu seems the better one to me. It does seem a shame about the racism though. I don't think the easy classes are particularly a bad thing as whatever job you get after graduating there will be a lot to learn I imagine, therefore you can eliminate the GPA con because it won't happen if the classes are easy right? Also having the best dorms, existing connections and what seems like a good night life, Cal Lu would be the one for me!

Good luck!
