4 GB dedicated VRAM instead of 16 GB shared memory is better/worse depending on workload.

Heat, battery life, fan noise, etc have been discussed to death so I'll gloss over those. Past that, the other huge thing is the screen:

62.5% sRGB coverage is a really garbage color gamut. Supposedly the "G513IM-HQ088R" gets you a DCI-P3 screen but I literally can't find that model available for purchase anywhere to check what it costs.

1920x1080 vs 3024x1964 is about 1/3 the pixel count of the 14" Mac. Or compared to the 16" 3456x2234 it's about 1/4 the pixel count.
