What's your favorite class size? Price excluded. What do you find yourself transforming most often or marveling at? Legends are nice as they harken back to the early days of Transformers. Simple and easy. Scouts are good, with that extra bit of complexity, but they feel a bit cheap or so with the hollowed out plastic. Deluxe are the nice mid point. Good articulation with ball joints and pivots. Sometimes very involved and a good size to them. Voyagers have that thicker plastic and feel very solid in hand. Nice size to them with some added detail. Human Alliance is off to a good start. Complexity, solid. Sometimes articulation is not the best. Leaders are nice because they are big and feel good in hand, but are sometimes a bit too complex and have a bit too much kibble around. Poseability might suffer from being taller and thicker plastic. Or any size that isn't listed... I guess I like me a good Voyager.
