Which one fits you
On wrists narrower than about 50mm, the Garmin Bounce 2 is the safer pick — it stays proportionate down to roughly 45mm, where the Samsung Galaxy Watch Ultra starts to hang over the edge. Above 50mm both sit cleanly, and the Samsung Galaxy Watch Ultra gives you more presence.
The Samsung Galaxy Watch Ultra wears larger than the Garmin Bounce 2 (47.4mm vs 43mm case), giving it more wrist presence — and needing a wider wrist to sit cleanly.
On the wrist the Garmin Bounce 2 feels lighter (26.5g vs 60.5g, case only).
Among the 312 43mm watches we hold thickness for, the Garmin Bounce 2 is thinner than 76%, so it wears flatter than its width suggests.
Among the 83 47mm watches we hold thickness for, the Samsung Galaxy Watch Ultra is thinner than 87%, so it wears flatter than its width suggests.

Garmin Bounce 2 vs Samsung Galaxy Watch Ultra on a wrist

- Samsung Galaxy Watch Ultra — 47.4mm case, standing 12.1mm 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.
