Which one fits you
Both need much the same wrist — roughly 45–61mm across the flat of the wrist. Neither will fit where the other won't, so decide on thickness, weight and features instead.
The Garmin Bounce 2 wears larger than the Samsung Galaxy Watch8 - LTE · 40mm (43mm vs 40.4mm case), giving it more wrist presence — and needing a wider wrist to sit cleanly.
The Samsung Galaxy Watch8 - LTE · 40mm is the slimmer of the two (8.6mm vs 12.4mm), so it slides under a cuff more easily.
On the wrist the Garmin Bounce 2 feels lighter (26.5g vs 30g, 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 509 40mm watches we hold thickness for, the Samsung Galaxy Watch8 - LTE · 40mm is thinner than 83%, so it wears flatter than its width suggests.

Garmin Bounce 2 vs Samsung Galaxy Watch8 - LTE · 40mm on a wrist

- Garmin Bounce 2 — 43mm case, standing 12.4mm off the wrist.
- Samsung Galaxy Watch8 - LTE · 40mm — 40.4mm case, 42.7mm lug-to-lug, standing 8.6mm 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.
