There's also Kloxo-MR Available (a community member took Kloxo and continued maintenance on it).
Compared side by side, bloated UI, features that should be options and addons. After comparing side by side with Webmin and Kloxo MR, I did not see a single reason to use Ajenti.^
No it's not. If you install a fresh copy it barely has components installed so it's not bloated. It's not buggy unless you fail to configure the component correctly.
