Choosing a laptop between 120Hz and G Sync is really up to personal preference as they have different kinds of specifications.A 120Hz laptop offers you a screen that has a refresh rate of up to 120Hz and a G Sync laptop offers you a screen that has the NVIDIA G Sync feature which can reduce stutters.
Let’s compare 120Hz vs G Sync Laptop below and identify which one between them is better.

120Hz vs G Sync Laptop – Make the Right Choice
A laptop with a 120 Hz refresh rate will display videos and video games a lot smoother than a usual laptop (60Hz – 75Hz). Movies typically run at 24 frames per second. So, a 120Hz laptop is basically for those who play games.
On the other hand, a G Sync laptop with an NVIDIA card will offer you smooth motions without tearing but does not do anything with monitor input lag which is seen in a FreeSync monitor. Most professional gamers use monitors with G Sync screens.

Battery Life | 120 Hz vs G Sync Laptop
Though battery life depends on your usage, a laptop with G Sync will have a better battery backup than a laptop with 120 Hz. Because a higher refresh rate drains more battery than G Sync does. G Sync only synchronizes with your GPU so it does not make a big difference between a G Sync laptop and a non-GSync laptop with GPU.
