COROS PACE 4

NO RUSH

No need to rush.

$249 at COROS

Better purchase today: neither. Both read NO RUSH. COROS PACE 4 costs $30.99 less today ($249 against $279.99), but that is not enough on its own to change the answer.

Better product: No clear winner. Pick by what each one is best for.

What reviewers say

ReportedNo outlet published a separate scored review of both, so reviews do not break the tie.

A pick needs at least 2 independent outlets that published a separate scored review of each product on the same scale, all of them favouring the same one, and an average lead of at least 5 points out of 100. Outlets with one owner count once. Scores are the outlets' own; iDevice did not test these products for them.

Key differences

Not enough for an overall lead: the Amazfit T-Rex 3 is ahead on water resistance only. It also costs about $31 more today.
