The action camera market has diversified into distinct form factors, each optimized for different use cases.

Traditional (rectangular with lens on the front):

- Examples: GoPro Hero, DJI Osmo Action, TL series

- Best for: General use, POV mounting, helmet, chest, handlebar

- Pros: Familiar, huge accessory ecosystem, best battery life, best stabilization

- Cons: Limited to pointing one direction at a time

Cube / ultra-compact:

- Examples: Insta360 GO series

- Best for: Ultra-light mounting (pet collar, drone, RC car, shirt clip), discreet use

- Pros: Tiny, lightweight (under 35 grams), magnetic mounting, unobtrusive

- Cons: Short battery life (15–30 minutes), no screen, limited resolution, fixed internal storage

360-degree:

- Examples: Insta360 X series, GoPro Max

- Best for: "Shoot first, frame later" — you record everything in all directions and choose the camera angle in editing

- Pros: No need to aim the camera; reframing in post creates impossible camera moves (the "invisible selfie stick" effect)

- Cons: Large file sizes, additional editing step required, lower per-angle resolution, more expensive

How to decide:

- Traditional: The default choice — works for everything, best performance per dollar

- Cube: Get this as a second camera for specialty mounts, not as your primary

- 360: Get this if you create content and want creative reframing options in post; skip it if you just want straightforward POV footage
