If you hate bloat you like Slackware. It doesn’t assume anything about how you want to use your computer, so it’s more painful for a lot of folks. Other distros will try to do things for you and will ultimately end up doing something someone doesn’t want. With Slackware you learn a lot and you get a rock-solid system that will do whatever you like, but you have to be willing to manage it.
Late reply, but I suppose you’re correct; I think the option to choose what to install, the lack of pre-created desktop stuff (“home/$username/Videos” for example) and the requirement that you handle software that isn’t in the base install all make a Slackware installation less bloated than most. Maybe not at install time, but over the life of the install you end up with less garbage IMHO.
