Parrot OS or Kali Linux
Best for Hacking X Ethical Hacking and Programming

Kali Linux is a bit demanding in terms of hardware requirements, and here’s why:

Kali Linux requires over 20 GB of storage, while Parrot OS can make do with just around 15 GB.
Kali is a little heavyweight, demanding a minimum RAM of 1 GB, while Parrot OS can make do with just 300 MB RAM.
Kali Linux requires hardware acceleration, using the GPU, while Parrot OS does not need this.
In terms of storage requirements and hardware capabilities, hence, Parrot OS makes a quick win over Kali Linux. An additional benefit is the deployment size after the installation; Parrot OS gets the upper hand when there is a limit on space and/or older hardware configurations are being considered.
