Robobo1221's Shaders 1.19 / 1.19.4+

Robobo1221 is one of the OG shaders. It was light years ahead of its time really and lacked nothing, even POM&PBR, so we can say that this shader aimed to make Minecraft as realistic as possible at that time. Unfortunately, the shader isn't updated yet and is still outdated, but you can still play it on the newer version just don't try some features like Pom, It breaks the shaders. The best part I noticed about this shader is the water, it's so tropical and reflects the surface accurately and realistically better than any shaders at the date this shader was released; it also changes the color theme depending on the weather and the time code.
