I have a couple of the early 4x33s (still M8s, friction adjustments), and several 4x28s. All are great scopes. Largest issue is the rifle on which the scope will be mounted. On the #1 Rugers, I absolutely prefer the longer tubed 4x28s. The 4x33s are just not as flexible due to their length. Make them almost as long as the 4x28s, and I'd gladly give up almost every other scope in the cabinet for them...
