I was not comparing the V-22 to helicopters, but to fixed-wing like the C-2. As you all may know, there is talk of buying V-22s for COD (i.e. shore to carrier shuttle flights). The C-2 is the same size as the V-22, but half the cost with 2-3 time more range.
V-22 salesmen are pressing the idea that it can do VertRep too, bypassing the need for the carrier stop. I was involved in Navy decision in the late 90s to drop the plan for 50 HV-22s in favor of the MH-60S. The V-22 was far more costly with many times the downwash.
If one googles "vertrep", you find this short video of H-60s doing impressive, agile vertrep.
From what I've read, a V-22 can do externals, but not well. I found only one video of a V-22 performing vertrep, and it explains why the Navy was right to dump the HV-22, and why it will stay with C-2s for COD.
And C-2s don't have to ditch should a gearbox fail.
