I think the Black Mamba based not only on the potency of the venom but the ferocity of the species.
There are some real bad boys in Australia too but the names escape me at the moment. I think they are black or brown snakes (referred to such informally) but don't recall the formal names of these serpents.
Tiger Snake in the land down under. Although the Funnel Web Spider is the one we were preached to about the most before going ashore in Sydney.
In the US, probably the Coral Snake...although the Mojave Green rattler ranks near the top, too.
Where I live, ANY rattler is all but extinct, our most common poisionous snake is the Copperhead...followed by the Cottonmouth.
When I was in the far east, it was the "Asian Two-Step", a tiny, highly venomous viper officially known as the Bamboo Viper. That and the Krait, which was called the Minute Snake for obvious reasons. Saw lots of very colorful sea snakes off the waters of Thailand....pretty nasty and aggressive, too.
