waze bought over by google so there is some sharing of traffic info between the 2.

i use separate garmin gps with malfreemaps for best routing accuracy. on phone, google maps followed by waze (thats just my experience and will differ from others for sure).

google maps and waze both got live traffic and are quite accurate. both will offer alternate routes based on traffic conditions. waze reports better especially for minor roads.

for searching places, google maps is amazing due to flexibility of google search.

fyi gmaps version 6 is better than the current one so i set my apps to manually update to avoid gmaps auto update to latest version.
