Aside from the larger footprint and additional capabilities of the Haas it would be happier doing its intended purposes which is to crank out parts all day everyday. That would not be my use case and would likely see failures happens from stagnation. The Tormach would be the perfect home gamer machine if they just went the one step further and put linear rails on it. That's the only real complaint I have about my home brew Chinese conversion is the occasional table stall on the X axis. It does everything else I need it to do as well as I need it to do it. A Haas for a hobbyist is just hard to justify.
