Question: is it worth upgrading from apple watch series 3 to series 5?
Answer: If you're running a Series 3, upgrading to a Series 5 will undoubtedly provide you with a plethora of advantages: a compass, an ECG, better heart monitors, upgraded Bluetooth, more storage, fall detection, a much bigger (and always-on) screen and faster performance. It's a far better device in virtually every way.
