OnePlus Watch 3 & Samsung Watch 7 share many similarities, but there are also important differences, such as quality, performance, features, design, and connectivity. If you want the best one between them, I Would recommend the OnePlus Watch 3 rather than the Samsung Watch 7.

- It comes with a traditional strap mounting system for simpler strap replacement and wider third-party style choices to match outfits or occasions, while the Samsung Watch 7 uses watch-specific strap fittings that limit universal replacement options.
