That would depend on the rest of specs as well as their price difference. i.e. buying a 144hz laptop that cannot run games at 144 fps is not a good option. In general, you cannot feel any difference between 120 hz and 144, especially for titles as mentioned above. It could make sense for shooter titles but again, 120 vs 144 is not even noticeable. Don't bother much with this, better monitor the rest of their specs to decide
