What does a new smart watch track that “last year’s model” doesnt? Like…what more do people need out of a watch???

My galaxy watch 4 tells the time, step count, battery, and heart rate. It takes calls and could send a text. It can open emails. I only use it for the first 3. Thats it. If it hadn’t been on discount I probably would still regularly wear a gshock because I don’t have to remember to charge it every 3 days.
