Slackware is the _most_ stable version of Linux. It is also
(perhaps) the fastest version of Linux, and because Slackware
relies _heavily_ on the usage of the Command Line, Slackware
basically forces you to actually _learn_ how to (properly) use
Linux. However, if you feel you may be dependent on GUI's (graphic
user interfaces) such as how things are done in Windows, Mac &
Android, then Slackware is definitely not for you. In short, if you
really wish to learn Linux and/or you need rock solid stability -
for use as a server, for example - then Slackware is the best
choice.
