My favorite acne product is Neutrogenia On-The-Spot Treatment -- it contains 2.5% benzoyl peroxide instead of 10% like most similar products, and 2.5% is just as effective as 10% but much less drying! It has done a great job of clearing up my acne and clogged pores without drying out my skin!
I also really like Cetaphil Moisturizing Cream, it clears up any dry skin instantly and doesn't clog my pores!
I don't think I've tried any products that I've hated, but I've tried some products that didn't work that well for my particular skin type. For example, ance products with salicylic acid as their active ingredient don't seem to do anything for my acne, but apparently they work for some people!
