It’s a subjective thing, but when a language clicks for you, work becomes pleasant. You get into (and maintain) a flow state. It feels as if you’re crafting something beautiful and elegant and simple. It’s the same reason people love painting, drawing, or sculpting with one specific medium over an other. They just like the aesthetic and process better.

Also, some languages just really stink— slow compilation times, obscure errors, loads of footguns and require much more care and focus on things which are orthogonal to the problem you’re trying to solve.
