I do. After using both for a while, there's not much difference. If you know your preferred voltages and you know the ohm's law conversion in your head, then vv is trusty. VW is solid but if I need to fine tune a flavor, I switch over to vv. It's nice having the option. VW is more of a set-it-and-forget-it thing. VV is more of a sweet-spot finder. The good thing about VW is you can go from a 3ohm carto to a 1.5ohm Nova without changing anything, and the output will be constant.
Are you finding you like different juices at different wattage? From juice to juice or vendor to vendor?
