As with any engineering question, the answer is: "it depends"
If you want an engine that doesn't have excess Vibration and Harshness (the VH in NVH), then the I6 is unquestionably better. However:
When it comes to packaging and weight questions, the V6 is "better", although the weight question becomes more of a wash when balance shafts are added to a V6 to solve VH.
More tradeoffs occur when a V6 is turbocharged - exhaust and/or charge pipes are longer (unless hot-V) which causes more lag, and other problems. An I6 is somewhat easier to turbocharge.
The long I6 crankshaft and camshafts may cause more manufacturing/maintenance/reliability problems than the shorter ones in a V6.
