Going to the source is always, always, always the best way!!
That being said, these reliable compendium sites serve the purpose of reminding me about certain software I've used and forgotten over the years as well as containing what I'll call some "homebrew gems."
But for anything listed that is available from the primary source, that's where I'll end up fetching it from (unless, of course, I recognize that the link given is directly to the primary source, and it often is).
