Which one fits you
Both need much the same wrist — roughly 49–67mm across the flat of the wrist. Neither will fit where the other won't, so decide on thickness, weight and features instead.
The Watch GT 2 Pro and Watch GT 2 Pro ECG share a near-identical 46.7mm case, so wrist presence comes down to thickness, lug-to-lug and weight.
The Watch GT 2 Pro is thinner than 76% of the 108 47mm watches we hold thickness for, the Watch GT 2 Pro ECG than 76% — so both wear flatter than their widths suggest.
