The ASUS ROG Flow X13 is very good for general use, while the Dell Inspiron 15 3511 is good.
The ASUS ROG Flow X13 excels in general use due to its powerful AMD Ryzen CPU and ample RAM, combined with a high-resolution touchscreen that boasts excellent color coverage and contrast, making it more versatile and visually appealing. On the other hand, the Dell Inspiron 15 3511, while offering more RAM, is limited by a less powerful Intel CPU and a lower resolution screen that lacks touch capability, which alongside its lower portability score and shorter battery life makes it less ideal for demanding tasks and on-the-go use.

The ASUS ROG Flow X13 has a better screen than the Dell Inspiron 15 3511 for general use, gaming and AI, engineering and design, software development, and content creation.
The ASUS ROG Flow X13 offers a display with vibrant colors and high resolution, making it ideal for general use and engineering tasks that require precise color representation. However, for gaming and 3D applications where smooth motion is crucial, its lower refresh rate diminishes the quality of the experience. The Dell Inspiron 15 3511, with moderate color accuracy and resolution, provides an adequate screen for everyday tasks and engineering work but, like the ASUS, falls short for gaming due to a refresh rate that doesn't lend itself to the fluid visuals gamers typically seek.

"The Asus ROG Flow X13 is not an off-the-shelf convertible. This quickly becomes clear when you take a closer look at the technical specs. The AMD Ryzen 9 5980HS is a state-of-the-art SoC with 8 cores and 16 threads, which also makes the 2-in-1 interesting as a work device. With 32 GB of RAM and a 1 TB SSD, gamers are also well taken care of. The dedicated Nvidia GeForce GTX 1650 Max-Q fits well into the overall concept and ensures a solid 3D performance. With the eGPU dock, which is equipped with a GeForce RTX 3080, the small convertible transforms into a full-fledged desktop replacement in terms of performance."
"The Dell Inspiron 15 3000 (3511) is a solid, if unremarkable, 15-inch budget laptop. It improves on many of the issues we had with the previous 3505 model, and with the inclusion of Windows 11, the 3511 is already a step above its competition. The lack of a USB-C port, the subpar speakers, and the dim display are drawbacks to factor in, but it's still one of the better 15-inch budget laptops on the market, especially when you consider it's under $400."
