Well i only have the ingy but had a good look at the VCO when in Brussels (the older one with the square date window), and Bulldog AR, this was a very nice watch, similar size and weight to the Ingy, i have heard the newer VCOs have the correct date window and good AR out of the box, I think the question here is which one you prefer, both are very good, both were designed by the Genta.
I wear my ingy for work but i dont think the VCO lends its self to an every day watch, it is little more elegant with the bracelet design and bezel, so i would say when and were you want to wear the VCO may answer your question, but the ingy in my eyes could be worn any where.
