Comparing the Samsung Gear VR and Snapchat Spectacles 3, it's easy to see that they are quite different in terms of their features and capabilities. The Samsung Gear VR is a virtual reality headset that works with smartphones and provides users with an immersive experience, while the Snapchat Spectacles 3 are augmented reality glasses.

The main difference between the two devices is their field of view (FOV). The Samsung Gear VR has a wider FOV at 101° compared to the Snapchats Spectacles 3’s FOV of 105°. This means that the user’s vision will be more expansive on the Samsung Gear VR than on the Snapchat Spectacle 3.

In terms of resolution, both headsets provide decent visuals but they differ slightly; while the Samsung Gear VR offers 2560 x 1440px resolution, Snapchats Spectacles 3 provide 1216 x 1216px resolution. Both headsets offer smooth visuals but there may be some pixelation on video content viewed on Snapchat Spectacles3.

When it comes to operating systems, both have compatibility for Android and iOS devices but as far as room scale tracking goes, only Samsung GearVR offers 360 tracking which makes for an immersive experience. In addition, both headsets support 60 Hz refresh rate ensuring smooth visuals without any noticeable lag or latency issues.

Overall, I feel like these two headsets provide unique experiences with different features tailored towards different users depending upon their preferences or needs. The Samsung GearVR is better suited for people who want an immersive experience with wide field-of-view whereas Snapchats Spectacles3 are great for those who prefer AR technology over traditional virtual reality solutions due to its portability factor and convenience of use in everyday situations such as travelling or commuting etc. Personally speaking I prefer using the Samsung GearVR because its wider FOV gives me a more realistic feeling compared to what I get from SnapchatSpectacles3 while still being able to enjoy all my favorite movies or games wherever I am thanks to its portable design.
