I've been a lace knitter for many years and I really don't like the Knitpicks lace yarns much. I might have been put off lace too if they were the first yarns I tried to use.
I've not used the Malabrigo but what I would recommend is get yourself some Jaggerspun Zephyr. It's the gold standard for laceweight yarns. The stuff is beautiful, it's got great stitch definition, blocks like a dream and is only a few dollars more than the Knitpicks yarns.
