Is 用一下 preferable to 用用 or 用一用?
All of them are suitable for the sentence, the difference is very subtle.

“用一下” is kinda formal, you can use this word in almost any occasion, having conversation with your friends, your boss, it's all fine.

"用用" and “用一用” is a little bit casual than "用一下".

But just like I said, the difference is so subtle that most people won't really care about it, especially if you're a foreigner.
