Which one fits you
Both need much the same wrist — roughly 49–68mm across the flat of the wrist. Neither will fit where the other won't, so decide on thickness, weight and features instead.
The Samsung Galaxy Watch Ultra wears larger than the Amazfit Bip 6 (47.4mm vs 40.2mm case), giving it more wrist presence — and needing a wider wrist to sit cleanly.
The Amazfit Bip 6 is the slimmer of the two (10.45mm vs 12.1mm), so it slides under a cuff more easily.
On the wrist the Amazfit Bip 6 feels lighter (27.9g vs 60.5g, case only).
The Amazfit Bip 6 is middle-of-the-pack for thickness among the 530 40mm watches in the database.
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.

Amazfit Bip 6 vs Samsung Galaxy Watch Ultra on a wrist
