The syntax is well suited for the most common case, which is regular wither methods for one or more known properties. I don't like the array syntax as a default. It has inferior DX for regular withers, and possible performance impact from the temporary array.

Again [1]: The choice of syntax cannot influence runtime performance after the code is compiled, because it is just that - syntax. It would be perfectly possible to specifically handle the case where the 'with' is followed by an array literal and then not construct a temporary array. In fact this is how the current implementation works: It doesn't actually support arrays yet, it just borrows the syntax of an array, because it more naturally extends to supporting arrays in the future.
