Here's a hint when looking at old 3.0 books: don't look so much on the name (like Quint whatever) or the publisher (even Green Ronin had some that were not that great), check out who wrote the book. One name that you will find working for a lot of comanies is Mike Mearls. His stuff is very consistantly good. Some of books of the Quint series for instance he wrote (Rogue and Wizard). Another very strong auther is Patrick Younts. He did Quint Monk and Wuint Sorcer, two great books. Mike is now full time with Malhovic and Patrick is with Mongoose.
Actually, I don't work with Mongoose anymore. I just work for myself, freelancing a few projects with Goodman Games currently, and publishing PDFs through Phil Reed's Ronin Arts.
But otherwise, you're right. The trick with any class book is to look at the names involved. Some individual companies have very strong reputations for overall quality, but that doesn't mean your own gaming tastes will necessarily mesh with those of the author(s) of an individual book.
I've been infinitely more satisfied as a consumer when I've followed the author name, not the company name.
That said, to throw my own vote in, I say 3rd party. There are some fantastic ideas out there in 3rd party land, and I think some of the work done by independant voices has really opened up the vistas of each individual class.
Green Ronin's Witches Handbook was a great book, for example.
However, I want to give props to some of WotC's old splatbooks. I really, really like Tome and Blood, primarily for some of the prestige classes - the Elemental Savant is my kind of spellcaster - and I also have a fond spot for the concepts behind many of Sword & Fist's PrCs, even though I found the execution wanting in many cases.
