ssh tabbed manager for linux

being a developer (sigh) I often need to access several ssh server, paying particular attention to discriminate between production and test servers....

After digging around for a good ssh manager linux, I these two are the best ones:

Another widespread tool is pac manager https://sites.google.com/site/davidtv/ which is more debian-ubuntu oriented.
