I go back and forth on Gateway. A microgravity research station beyond LEO would be pretty helpful. Beyond that, though, it won't literally be part of a Mars transit architecture like some long forgotten proposals, and stopping there on the way to the surface is unnecessary added delta-v. SLS+Orion also can't fly often enough for Gateway to be its own destination or continuously crewed.

In my perfect world, there'd be continuously crewed lunar surface and orbital stations with commercial vehicles flying public and private missions to both. One day...
