I think (and correct me if i'm wrong) but you both have different triple screen fov's. From what i can remember trying yours out Adrian, it was set quite far away and so the effective fov of your monitors would be much less than someone with the same triple screen arangement but located much closer (so they fill their peripheral view with the game). If the above is true, i could see why you would say that about the rift vs your triple. Perhaps Spinelli has his triple's much closer which could make a difference in his judgement of how "spacious" it is when comparing a rift to his setup. Btw, have you tested a rift yet Spinelli?
