I seem to be the oddball here :-) . I love aptitude. While autoremove is very much automatic as you said it still shows you what it is going to do before it does it.
0 packages upgraded, 0 newly installed, 0 to remove and 0 not upgraded
I like this because many times it is telling me what packages I don't really need anymore. It is not always correct which makes the above commands I mentioned in my previous reply more important.
However, as mentioned, yes pick one only and stay with it. if apt-get works for you or anyone else, then that is all that matters. there is no right or wrong way of doing it. The great thing about linux is that there are so many choices and we have the freedom to choose what we want.
I wonder though. I can't be the only one who uses aptitude, am I? lol
