Piggybacking on the [motivation in winit]: `lazy_static!` is a macro whereas `once_cell` achieves the same using generics. Its implementation has also been [proposed for inclusion in `std`], making it easier to switch to a standardized version if/when that happens. The author of that winit PR is making this change to many more crates, slowly turning the scales in favour of `once_cell` in most dependency trees. Furthermore `lazy_static` hasn't published any updates for 3 years. See also [the `once_cell` F.A.Q.].
