Best map?

Well, as an old CS player (since 1.4 non steam/hl mod) my personal fav and still fav btw, was Dust2, its just perfection, obviously it has some flaws, but form the whole competitive map pool, D2 was the only map who maintained its main core, with minor tweaks over the whole history of CS. Already did a full "Road to Global" playing dust2 only, idk, a lot of people say the map is unbalanced and prefer the mainstream maps. I will stick with D2 as my forever best map
