Somehow Ford revamped Sync faster than VW has optimized their software.
No problem with lag at all. The nav and trip planner is actually way better than Google maps IMO. It will direct you where to charge and for how long on longer trips. The lane guidance with the light strip in the dash and directions in the gauge cluster are extremely useful.
It is annoying that media and climate controls are all on the touch screen. However I learned to just set it to auto and use the dedicated capacitive temp buttons to tweak a degree or two.
For radio and music, I almost always use the buttons on the steering wheel.
The driver assist features work very well on the highway, standard lane center and adaptive cruise.
The mobile app sucks and only controls charging and remote climate.
Overall a good practical car that's solidly put together. It's extremly quiet and has a shockingly good turn radius. My one complaint is that it's a bit bloated weight wise. VW is moving back to physical controls in their newest models, but North America seems to be destined to only receive big crossovers for now.
