Epic Breeding Island is simply a second Breeding Cave that has a slightly better chance at breeding rare dragons, and Dragonsai Gem Tree allows you to gift gems to up to 6 friends per day. Neither is significant. It's more between whether you want to be able to breed two pairs of dragons at once, or send double the gifts you're usually able to send.
