Turbulence that would push an aircraft up or down will have the same effect on either design. However, turbulence that would typically cause a plane to roll quickly (such as hitting some sort of vortex or wake from another plane) should have less effect on a plane with a more widely distributed mass. On the other hand, once you start the big V plane rotating, it will be harder to stop rotating (take longer, unless the rotation energy is so great that the comparatively short wings simply cannot compensate). We are at the point of fly-by-wire where there is usually a computer between the human and the control surfaces. This enables truly unstable aircraft (like the awesome F117 stealth fighter) to fly when they are inherently unstable designs. But as evidenced by the 737 Max debacle and the long ago A320 (320?) issue, sometimes the computer makes an unfortunately poor decision and does a bad thing. Point is, we are already there, so we might as well allow the computer to make a V fly wonderfully and save a lot of fuel and cabin noise.
