The country's ranking in global output has been _____ for quite some time now.
What is an idiomatic adjective, or adjectival phrase, meaning "very positive" or "very good" or "very high", to put in the above sentence. Or are each of these three options idiomatic when we talk of ranking?
Thesaurus give a lot of options, among which "outstanding" sounds not a bad option to me, but I still don't know which one is idiomatic when we are talking about rankings.
I am not looking for words that add other meanings. For example, "promising" seems to me to add a sense about future and consequences, and that is why it is not what I am looking for.
