I'm waiting a few months to upgrade my main machine (which is El Cap) to High Sierra, but I'm blown away by the subtle-yet-useful changes (like photos), the better graphics performance, the improvements in the responsiveness of the UI, the improved RAM efficiency (which I have noticed is especially pronounced on 4GB RAM models), and reduced CPU loads that correspond with disk activity. This one is definitely worth updating to (IMO it is also worth making a bootable clone before updating, using a program like Carbon Copy Cloner).
