I like AccuFeel, but wouldn't consider it a must-have. I have no way of knowing if the squishiness on taxi is realistic or not, but I will say it seems more realistic than the feel like you're driving a car without out. It adds another element to taxiing. The main thing I like is the rattle on landing. Having watched cockpit videos, landing is not like lying down on a feather bed, but there's a certain amount of shake, rattle and roll. At least that's my largely uniformed take. At least it's all highly configurable, so if you don't like something, you can easily adjust it from airplane to airplane.
