Would not advise Debian to a new user. Old packages and difficulties installing non free software may frustrate people.
I did use Debian as my daily driver and I have it in a few servers, it is a very good system. But to the common user stability is not the priority which should prevail over everything else.







Yes, the keyring is a pain, also because I like to manually check all the keys. But then what often happens is that lots of configuration options have changed and you have to go through bunch of software to find out which exact package is now misconfigured and makes your system not work as it should.
