AFAIK, JuiceSSH is still closed-source, which means I and a lot of others won't be using it. AFAIK, there's no good ssh clients for android, only tolerable ones.
I'd love to be proven wrong about that though.
Have you read the source of connectbot? Have you compiled the version you are using yourself?
If not, the version of connectbot on the play store is no different then JuiceSSH.
This. I use JuiceSSH everyday on an Android phone to remotely admin my OpenWRT router and I love it. It's quite simple and meet my needs.
