I use ".test" to respect RFC-6761 [1] which reserves four TLDs: .example, .invalid, .localhost, and .test; as many of us already know ".dev" is owned by Google [2] and both ".local" [3] and ".app" [4] are reserved for the root zone so it doesn't makes any sense to use any of them for local development. So I use ".test" for my personal projects and ".[company]" for projects related with my job.
