That'll depend a lot on the context and the client, I imagine. Comptime and the minifier can be distributed in a fairly standard way as part of an NPM package's dependencies, so if you're shipping to a system that can handle NPM, then comptime doesn't really add much. But if the client doesn't have a JS runtime installed or can't easily access the NPM ecosystem, then I can imagine shipping the C preprocessor could well be easier than juggling two different tools.
