The Acer Aspire 3 14 is a budget-friendly option that's lighter and has a longer battery life, targeted more towards general use with moderate performance capabilities. The Lenovo Legion Slim 7 16" is pricier, but supports more demanding tasks such as 3D rendering, machine learning, or engineering applications with higher performance parts, a larger and higher resolution display, and features suited for intensive gaming. Consider the Acer if you prioritize portability and value, or choose the Lenovo if you require a machine for performance-intensive tasks and can afford a heavier laptop with shorter battery life.

NotebookCheck

Benjamin Herzig | November 2022
"The Lenovo Legion Slim 7 is a slim Legion notebook that is just as excellent with Nvidia & Intel. However, the Legion Slim 7i slightly sullied by lacklustre battery life. You get a slim aluminium chassis, great input devices, decent port selection, fast high-quality WQXGA display and great performance. Supporting Thunderbolt 4 is one advantage of the Intel/Nvidia model tested in this review. Moreover, this variant has slightly higher CPU performance as well as better GPU performance in certain applications (e.g. CUDA-based apps). The Lenovo Legion S7i is thin, premium and performant – but less efficient than its AMD counterpart."
