I often need a dictionary to translate a text, but a proven one with up-to-date translations. Which one can you recommend?

I agree, it's a tough choice. There's a lot of variety now, and it's hard to settle on one option. It all depends on how you're going to use it and what level of difficulty you expect from it

Yes, it's very difficult to choose one thing right now, the variety gets in the way. For example I use https://examplum.com/ , I like the interface, I like it simple, clear and concise, there are no unnecessary details that will distract from the work. Consider this option, I think it will suit you. So far none of those to whom I advised it, have not been disappointed.
