Verdict

The call

The clearest difference is update cadence: E3/E4 TAG Heuer Connected at every 5 weeks against CITIZEN CONNECTED's every 4 months. E3/E4 TAG Heuer Connected also leads on rating (4.9 vs 4.7). CITIZEN CONNECTED's advantage is monetization model (free vs ad-supported). On price, review sentiment, ratings volume and ads there is nothing between them.
