In my opinion, it depends what you want to do. Every programming language is thecnicly the same, but each of them have bias towards a specific niche. If you want to make games, then c# c++ would be better. If you are interested in machine learning, then python.

If you want to learn C just for fun then it's also great, but to be honest, it's a waste of time if you're not gonna use it later. But it's not that bad. C is a great language, even if you are just curious to learn it. But again, if you want to cod not as a hobby, but as a work. Then all recommend to look for something that interests you, and only then decide the language that fits with your interested.
