So I'm now down to 2 laptops, the Acer v 15 Nitro Black Edition, and the Asus GL502VM. Both have similar specs, however, the Acer has much better battery life but the Asus has G-sync as well as an NVME PCIe slot. So my question is, are Acer laptops dependable and reliable? Also how useful is G-sync for gaming? And similarly, what are your guys general thoughts on each of these two laptops? Thanks
