The Acer has a higher resolution display with a WQXGA panel, which will offer sharper images and potentially better color accuracy. It also has a higher refresh rate, beneficial for gaming.
The HX series processors are generally more powerful than the H series, offering better performance, especially in CPU-intensive tasks.
The Acer Predator Helios Neo 16 seems to have a slight edge, especially with its higher resolution and refresh rate display, potentially more powerful CPU, and additional features like Thunderbolt 4. However, the HP Victus 16.1" is still a strong contender, especially if it comes at a lower price or if you prefer its design and build.
