Are rotating convertible car seats worth it?

Reviewers across r/toddlers and r/CPST say rotating seats like the Graco EasyTurn 360 and Turn2Me genuinely save your back when loading a child. The trade-offs flagged by reviewers: they are pricier, the Turn2Me only rotates in rear-facing mode while the EasyTurn 360 rotates in both modes, and one reviewer noted the EasyTurn must be uninstalled to change the recline.
