I don't know a single professional pilot who prefers anything other than vector charts. Jepp FD Pro is only vector charts with no standard Hi/Low Enroute chart. That's the FAA approved charting "document" for most of the airlines. They all fly IFR.
I'll concede that 150 KTAS or less makes the Enroute chart more usable. If you're doing 200+ KTAS you end up zoomed out more and the chart is less usable.
