The question should be which is better Royal Road vs Card College Vol.1 as these 2 books cover most of the same stuff only CC is an updated version.
The 3 Card College books you are asking about teach tricks and routines that require no sleight of hand, where Royal Road is a beginners lesson in sleight of hand. So in all actuality the question you are asking is, which is better tricks that use no sleight of hand or tricks that use sleight of hand? The answer is both are very good. If I was just starting out in magic, to me, it would not be worth it to spend $90 - $100 on 3 books where you are not going to learn any sleight of hand where you can spend $10 on a book that is a serious stepping stone for beginners in magic.
The description for Light, Lighter and Lightest all say the book are designed for beginners and that may be true, but I think these books would be better for someone already proficient in sleight of hand. Again, this is just my opinion, but I think it would be a waste of time to learn self working tricks in your first year in magic instead of beginner sleight of hand.
