I've been crocheting about seven years now and I absolutely love it. I want to learn to knit as well; not sure when that'll happen but eventually it will.
I use Red Heart Super Saver a lot, because it's cheap and available in so many stores. But my favorite yarns are Caron Simply Soft and Lion Brand Vanna's Choice. I've also just used Lion Brand Pound of Love for the first time. I love it. It's soft and has a great texture. It might join my favorites list.
I also don't shy away from the novelty yarns and love Lion Brand Fun Fur and Festive Fur. My only complaint about the fuzzy yarns is how hard they are to wash. The fur gets matted down easily and then the item just looks like crap. Ah well. I just have to be more careful washing and drying items that have novelty yarns in them.
Well, I could gush for hours about yarn. I have a craft blog, Oh Frog It, where I blog about my crochet and other craft projects. Check it out.
