These are not much of a comparison since they have different types of venom. Also, the Brazilian Wandering Spider's venom is not as good at killing humans as the Black Mamba's venom is. So the point goes to the Black Mamba.
The Brazilian Wandering Spider, also known as the armed spider or banana spider, is known for its aggressive behavior and potent venom. It is considered one of the most venomous spider species in the world. These spiders are called wandering spiders because they do not build webs to catch prey, but instead actively hunt for food.
The Sydney Funnel web spider is the most poisonous spider on earth, causes comas, seizures and death within the hour of the bite. Those who believe the wandering spider (or more officially, the banana spider) is the most venomous are incorrect and it is only reported the most dangerous because there are more reported bites, but it is not as venomous.The above statement is actually incorrect. The Brazilian Wandering spider's venom is far more potent then that of a Sydney Funnel-Web. It hosts a neurotoxin that is near-identical to the one of a King Cobra and can cause paralysis in a matter of minutes. Death in roughly an hour.The most defining difference in deadliness between the two spiders is the fact that there is a cure for the Sydney Funnel-Web spider's venom. While the is but only a treatment for the bite of a Brazilian Wandering spider. The Brazilian Wandering spider's venom can kill just as quickly as a Sydney Funnel-Web spider's venom can, but can also cause permanent damages.

The spider you are describing is likely a nursery web spider. These spiders are known to lay small clusters of white, round eggs in a protective nursery web made of silk. The female spider will guard the eggs until they hatch, releasing spiderlings that disperse into the surrounding environment.
There are a few spiders in the world that are said to be so highly venomous that they count as being deadly. It is commonly believed that the Brazilian wandering spider is the most venomous spider. There have been over 7000 recorded bites. If a person is bitten by this species there is a good chance that death will occur if the spider delivers a substantial dose of venom unless antivenom is used. The toxicity of their venom per unit of volume is high, and each spider produces much more venom than other kinds of deadly spiders. The Black Widow Spider is very venomous. There were 63 recorded deaths in the United States between 1950 and 1989 alone, although recently the number of deaths has reclined because of the use of antivenom. Worldwide the widow spiders kill the most people because they are found in so many places. In some of these places living conditions put people in more frequent contact with widow spiders, and health care is poor. People who are bitten may not receive antivenom. Usually only children and the old and infirm will die. Healthy adults rarely die. The ratio of body mass to venom volume is crucial. A spider that can deliver enough venom to kill a small child may not have enough to give an adult serious trouble. The Australian funnel web spider ranks very high too, as its poison can kill in 2-3 days, although in one rare case death occurred within 15 minutes. The venom of these spiders is less toxic than that of the Brazilian wandering spiders, and each of them has less venom than does a Brazilian wandering spider. However, they generally deliver all of their venom if they decide to attack, whereas the Brazilian wandering spider frequently gives partial envenomations or even just dry bites.
If you're asking how many people die due to spider bites in a year, well... That completely depends on what part of the world. Some places there are zero, some between fifty and one hundred. 110
