For sit down, say flight, driving sims and productivity, then things to look at to compare would be things with a cable and no local compute taking weight, heat and component cost. There's the Pimax Dream Air SE and the Big Screen Beyond 2e as two recent updates in the ball park of Steam Frame pricing. Both that have eye tracking for better high resolution performance. The Pimax has a variable quality reputation and the Big Screen Beyond requires a deprecating Lighthouse tracking system, so no easy answers. None will be as smooth an experience of the Frame but are more geared to head mounted display.
