The DX80, MS12 and X70 all deliver their power completely differently, it isn’t anything like owning three lights with different power levels.
The DX80 has by far the largest hotspot and narrowest spill, so to the naked eye it appears to be the most powerful as all the light is concentrated into your peripheral vision. The MS12 has the widest but dimmest spill but a wider hotspot than the X70. The X70 is just a massive area of super bright spill, though it does throw the furthest it’s not a wide beam.
In my opinion all lights are equally good. Each has pros and cons. I wouldn’t choose the X70 or MS12 over the DX80 based purely on lumens due to how the DX80 uses those lumens. Though it does mean lumens aren’t right at your feet.
Glare isn’t that bad on them as they aren’t that high on candela. They are like football stadium floodlights.
