Do you mean rerouting? Google Maps is tuned differently than Waze, which caters to drivers looking to shave off minutes or even seconds. It tries to keep directions simple and easier to follow (e.g. not making a large number of turns), even if that means a slightly slower route. That was a deliberate product decision, at least until a few years ago.
What kind of incomprehensible directions and business names are you referring to?
Waze feels more like the R&D app for maps. It doesn't shave seconds or minutes off my time, but what it does do is constant A/B testing to see if another route could be faster. I know the area fairly well and I routinely ignore the route Waze wants to send me unless there is a clearly identified problem on the normal route, and when it re-routes to the path I chose, it's a minute or two shorter. Why did it try to send me down the slower route in the first place? Waze pulls this crap routinely.
