Which one fits you
Both need much the same wrist — roughly 48–65mm across the flat of the wrist. Neither will fit where the other won't, so decide on thickness, weight and features instead.
The Amazfit GTR 3 and Amazfit Stratos Plus share a near-identical 45.8mm case, so wrist presence comes down to thickness, lug-to-lug and weight.
The Amazfit GTR 3 is the slimmer of the two (10.8mm vs 12.7mm), so it slides under a cuff more easily.
On the wrist the Amazfit GTR 3 feels lighter (32g vs 60g, case only).
Among the 212 46mm watches we hold thickness for, the Amazfit GTR 3 is thinner than 93%, so it wears flatter than its width suggests.
The Amazfit Stratos Plus is middle-of-the-pack for thickness among the 209 46mm watches in the database.
