I’m not sure what you are responding to. “Gives nicer looking gradient” than what? CIELAB is a very simple model, which has been very successful but also has various deficiencies. In particular it specifies a broken method of white point adaptation (this can be swapped out), and involves a nasty blue-purple hue shift at constant CIELAB hue which can have big impacts on images put through a gamut mapping algorithm in CIELAB space, e.g. for printing.
