There are AWS SDKs for several different languages: C++, Go, Java, .NET, Node.js, PHP, Python and Ruby [1]. It appears that some of these SDKs are more complete than others (for example, CloudFront only seems to support Java, .NET, PHP, Python and Ruby [2]).
Which SDKs are the most complete and/or the highest quality? Which language(s) would you recommend (or not recommend) using to interact with AWS?
Are some of these SDKs more "official" than others?
