I’m not sure. In this thread there is a benchmark: [[ANN] LightSumTypes.jl v4 - #15 by Tortar](https://discourse.julialang.org/t/ann-lightsumtypes-jl-v4/116741/15)

which suggests that on 1.11 the different is small or even against sum types. But I’m not following closely these developments.

(personally I would prefer to use the package, to guarantee that it is fast on 1.10 which is the current LTS)
