There are some people here with collections of their own homebrew or of their favorites others have made, but nothing comprehensive. There is just so much of it, plus the quality and level of completion could be anywhere, and we all have stuff we and more interested in.
I know the MTGSalvation forums (neckbeardy as they are) actually have a pretty good review process for a deck type called "Commander" or "EDH" that can get a [PRIMER] tag put on them after they go through the ringer. I know that's definitely that forum's thing, but it could be neat to have a review process like that here. I'm just not sure who would want to be a reviewer for a homebrew, or what the parameters would be. Also, since we can't edit OPs, it'd mostly be through Google docs or Dropboxes...
Anywho. Like Ciaran said, the quality on the forums runs the gamut. Some are phenomenal, some are less so, and many are very specific archetypes or custom classes/abilities/feats/etc. for particular campaigns or games. It's a little hard to judge them since it's all so subjective, unless we just go the route of asking if something could feasibly be published in a companion product or solid 3PP thing.
I'd say your best bet is to scour the forums and grab the things you like and keep the links all in one place.
I have no collections to recommend. I just click on stuff as if appears in the forum.
And I have no idea what or who lords blade is.
