Which one fits you
Both need much the same wrist — roughly 45–63mm across the flat of the wrist. Neither will fit where the other won't, so decide on thickness, weight and features instead.
The Amazfit Active 2 wears larger than the Huawei Watch 5 - 42mm (43.9mm vs 42mm case), giving it more wrist presence — and needing a wider wrist to sit cleanly.
The Amazfit Active 2 is the slimmer of the two (9.9mm vs 10.5mm), so it slides under a cuff more easily.
On the wrist the Amazfit Active 2 feels lighter (29.5g vs 51g, case only).
The Amazfit Active 2 is thinner than 99% of the 44mm watches we track and the Huawei Watch 5 - 42mm than 89% of the 42mm ones — so both wear flatter than their widths suggest.
The Amazfit Active 2 is 1.9mm wider, 1.4mm longer, 0.6mm thinner and 21.5g lighter than the Huawei Watch 5 - 42mm. Both are circular.
