Summary from trustedreviews:
Design: The Versa offers a more universally appealing design; most people are likely to prefer its looks over those of the Ionic. Both have the same 1000 nits display, which is excellent.
Specs: The Versa sacrifices its built-in GPS in order to hit a lower cost. Dedicated runners will miss this feature. Otherwise, the specs are largely the same.
Apps and smartwatch functionality: It’s a draw here, too. You’ll get exactly the same experience across both devices.
Battery life: Another tie. You can expect 4+ days of battery life from both.
Price: The Versa is cheaper at £199; the Ionic is widely available at £249. You’ll have to decide if you want to sacrifice GPS for a more attractive design and lower price.
