Which one fits you
On wrists narrower than about 60mm, the Samsung Galaxy Watch6 - Wi-Fi · 40mm is the safer pick — it stays proportionate down to roughly 43mm, where the Samsung Galaxy Gear starts to hang over the edge. Above 60mm both sit cleanly, and the Samsung Galaxy Gear gives you more presence.

Samsung Galaxy Gear vs Samsung Galaxy Watch6 - Wi-Fi · 40mm on a wrist
Put Samsung Galaxy Gear and Samsung Galaxy Watch6 - Wi-Fi · 40mm on the same arm, sized to your own wrist, and turn it. Side by side or stacked on one spot, whichever answers the question faster.
- Samsung Galaxy Gear — 37mm case, 57mm lug-to-lug, standing 11mm off the wrist.
- Samsung Galaxy Watch6 - Wi-Fi · 40mm — 38.8mm case, 40.4mm lug-to-lug, standing 9mm off the wrist.
Whether that clears your wrist edges is the question worth answering, and it depends on your wrist rather than on the case diameter.
