Agreed. I find Waze has more aggressive rerouting. Maps tends to stick to simple navs at the expensive of a few minutes. Waze will zig-zag me around town. I do find both apps make my phone hot and gulp battery though.
Waze has rerouted me around catestrophic traffic jams multiple times, both cases having a companion launch apple/google maps and they were more than happy to send me right through it.
