harmony cruz vs. Harmony youth booster seats

[HIU8]

Is the Cruz that much better than the regular youth booster? I saw the cruz today (after purchasing 2 of the harmony youth seats over the weekend). The seat seems deeper. Do the side wings really add that much safety to the seat?

IMO SIP is more important for head/torso, but I guess if it helps keep the child in place better, it could theoretically help with that. Hard to say. I have both and the Cruz is narrower, but deeper. It is somewhat harder to buckle in tight spaces because you have to get the lap belt down in the space under the arms and the side wings make it harder to access the buckle.

My kids prefer the Youth Booster (LiteRider), they don't love the Cruz (at least in a floor comparison test, they never complain about any of them in the car, at any rate).
