Using nano is more comfortable in my opinon. It is also nice to install midnight-commander to your Linux env for easier navigation in the system.
// Installing midnight commander via apt-get
apt-get install mc
// running midnight commander with sudo rights for editing system files
sudo mc
I also recommend configuring your midnight-commander so that when you leave your instance it stays in the directory you left it in, see here section "hold your horses" : http://klimer.eu/2015/05/01/use-midnight-commander-like-a-pro/
The link also gives you an overview of what midnight commander has to offer.
