@lukeed/ms is a fork of vercel's ms that is consistently faster (up from 40% to 2x faster), though with a slightly bigger installation size (9.4 KiB compared to 6.7 KiB due to @lukeed/ms shipping tripple CJS/ESM/UMD while vercel's ms only ships pure CJS, which is just not a huge deal anyway).
vercel's ms is mostly used by the popular debug library, while @lukeed/ms usage is growing rapidly and is being adopted by Hey API and the Fastify ecosystem.
