Asus Zen Watch vs Samsung Galaxy Watch 5

This smartwatch has powerful hardware (for a watch) and costs only $99. It's the best value smartwatch out there that doesn't compromise much on design - arguably the most important factor when choosing a smartwatch.

The Amoled display provides rich colors are true blacks which is even more important on a watch (likely it will be displaying black very frequently). From a functionality standpoint, a square display fits more content on it, especially when the entire UI is based on rectangular cards.

The bio sensor measures your pulse, and keeps track of your relaxation level throughout the day (a lower pulse means you are more relaxed). It's neat to see what part of the day you are stressed out during, and if you notice patterns during high stress times you can change that.

The automatic workout tracking on the Galaxy Watch 5 is super accurate, pausing and resuming within seconds of you starting/stopping.

The Galaxy Watch 5 comes with all the health tracking you could want - heart rate, ECG, as well as body composition and continuous stress measurement.
