The ASUS ROG Zephyrus G15, with high refresh rate and powerful Nvidia graphics, is better suited for gaming and visually intensive tasks. However, its battery life is moderate and it’s heavier, which could be a concern if you need portability. The Lenovo ThinkPad Z16 features an OLED screen with higher resolution, potentially better for creative work where color accuracy matters, and is slightly lighter with longer battery life, making it more portable and suitable for general use and business applications, despite a lower refresh rate which is less optimal for fast-paced gaming. The ThinkPad generally costs more but offers higher storage capacity. Give Feedback

"As long as you're aware of the fact that the GeForce RTX 3080 laptop version can only unfold its potential to a limited extent due to Asus's low TDP setting and that it can be slower than a fast RTX 3070 laptop, the ROG Zephyrus G15 GA503Q cuts a fine figure. One of the biggest highlights turns out to be the WQHD panel, since it attracts customers with 165 Hz, relatively fast response times, FreeSync, and good color-space coverage. Other selling points are the surprisingly rich sound, the long battery life, and the sleek design. In terms of looks, the white edition stands out nicely from the competition."

"Lenovo’s ThinkPad Z16 tries has some success in its effort to tweak the ThinkPad formula. The laptop is attractive, yet still tame, and material quality is on par with the best Windows competition. I also like the smooth, responsive haptic touchpad and the wide range of modern connectivity. Yet the Z16 doesn’t fix ThinkPad’s typical weakness: value. Starting around $1,550, and more typically near $1,700, the Z16 finds itself facing alternatives that have better performance or an improved display for the same price, or less."
