Custom Distributions – Which Linux Distros Is Best for the Intel Core 2 Duo 2 GB RAM

I will install Linux in my system, which is very old, and I will use it for occasional tasks and basic programming. Configuration:

Intel Core 2 Duo processor E7400 2.80 GH;
Ram 2 GB; 500 GB disk;

I already use Ubuntu Disco 19 on my laptop. So I want to try something new, lighter and faster. I will completely remove the windows and install Linux. Suggest an operating system that runs fast in this configuration and does not freeze.

Do not give the best suggestion of any Linux distribution outside of Ubuntu 19
