I'm a big fan of early-edition clones. I like their low page-count, and all the vast room they leave for rulings rather than rules. I don't think I've met an early edition clone I didn't like. Right now, Immersive Ink's Delving Deeper is at the top of my list, and I plan to use it the next time I start a new campaign.
It's not so different in content from other clones. But it has (IMO) the tightest, most intuitive organization of all the early-edition clones. It also fits into my personal "sweet spot" of being rules-light, while also having just enough rules on things I want to have already ruled for me, while leaving out what I don't need.
Granted, that's all a question of personal taste, and it may not be your cup of tea. But if you aren't already familiar with Delving Deeper, you might want to give the rules a look. The free reference rule pdfs are available at the Immersive Ink Forum. The $4.78 print version is available at Lulu.
