Although Camera is not a deciding factor for the gaming devices both the ROG and Legion have great camera specs. 

Legion has dual rear cameras of 64 Mp and 16 Mp having aperture of f/1.9 and f/2.2 respectively. The front camera is 44 Mp.  

The Legion phone has a camera at the centre of the device on the rear side and the pop up selfie camera is also at top of the phone at centre in landscape form. This allows the gamers to game conveniently even when using the camera. There are some special options available in front cameras for streaming online . 

The ROG on the other hand has a triple rare camera, 64 Mp f/1.8, 13 Mp f/2.4 wide angle and 5 Mp macro camera. The selfie camera is 24 Mp. ROG phone’s camera are not designed for streaming. The front camera is on the bezels and the rear camera is also normally placed. Basically you can’t stream through ROG when playing games. 


Design is observably different devices. Legion definitely has an edge in terms of design for a gaming smartphone. The company made this design to help gamers in streaming and allow them to use cameras while gaming. Also the advanced cooling system needed a place . 

ROG on the other hand has a more conventional design. The in built cooling system is not that great but you can add using the POGO pin. 

The performance is similar in both the devices but Legion has an edge due to cooling system and response rate. 

So, you need to consider the fact that with Legion you will not be able to perform day to day tasks that easily due to its design and the camera positioning. The ROG on the other hand can be a daily driver or a gaming beat as per the requirements.
