Yandex can also provide cheaper ex-USSR coverage even if quite limited too. At least it is still alive, has correct wuality, covers a few countries Google doesn't have and even got Uzbekistan very recently!
We can also think about Baidu / Tencent Maps to have a Chinese version: good quality overall, correct coverage but very slow loading as it is behind the great Chinese firewall...
Wonobo from India exists too but it may be too poor though.
Maybe other services exist but I do not know them yet.
