I guess we all have different experiences and memories.
Navigation is in the end also dependent on how/where it is used.
While
@r1200gs4ok ,
@David99 and (some others for sure) have probably genuine good experience, mine was that it was not doing a good job neither at routing or rerouting, estimating correct times of arrival and taking into account traffic conditions.
The new one is spot on in term of timing, always close to what Waze proposes (to me Waze is the most traffic condition aware solution) and reroutes fast and intelligently (not whining about returning to the initial route at all cost until you are far enough to make the effort or recalculating the best route).
And again, maybe Europe with his historical older routes and higher density, has more complex intersections, but those nice simplistic static pictures often where wrong and not useful.
But all of the above can indeed maybe vary pending on where you live or drive to/from.
