Why size and weight matter:
Weight is important for action cameras because we often mount them on helmets, or hold them at the end of a selfie stick while moving. Therefore a heavier camera can be dvifficult to use or uncomfortable. Weight is even more crucial for certain sports like road cycling or running.
Battery life
The Action 3 offers a much larger battery capacity. The Action 3 has a removable battery whereas the Theta X's battery is not removable

Why battery life matters:
Nothing worse than running out of battery just before capturing the best footage of the day! A long battery life is reassuring and convenient when shooting footage outdoors where options to charge are limited. Even the use of a power bank can be tedious or simply impossible like when filming watersports. Having removeable batteries allows battery swapping on the go which further extends your runtime.
Storage
Only the Theta X features built-in storage. Both the Action 3 and the Theta X support SD cards.

Why storage matters:
High quality footage can quickly take up lots of space and insufficient storage can soon be frustrating. Having a large amount of storage and the possiblity to extend it or swap SD cards while on a outing will ensure you will always be able to capture the footage you want. However, smaller, wearable action cameras often rely on built-in storage because of their small size.

Only the Action 3 offers HDR video.
