I agree, I find it easy to identify in any season. We have few plants that resemble it or its growth habits in anything but a superficial way, plus poison oak is much less variable in leaf size and shape than poison ivy. The buds and stem tips are especially good giveaways, but I didn't really realize it until I lived somewhere with multiple species of sumac.
