Having quit both, weed was worse. Weed stays in the system longer and affects almost every system of the body.
In weed withdrawal you do not sleep (I was awake 4-5 days in a row, and even after that, only 1-2 hours per night), had intense hot flushes, sweating, inability to control my body temperature, nausea and vomiting, complete lack of appetite, extreme anxiety, complete depression and cratering of pleasure. You will enjoy nothing for 3+ months, and enter perhaps the greatest bleakest dark period of your life in which you try to kill yourself (I did). But I know now I was not myself.
Weed completely messes with your dopamine system and rewires it, and you become incapable of enjoying anything without it. You have to get high to eat, or have sex or masturbate or play a video game or watch TV or doing anything. It can make you content or happy for years of your life to do nothing, and it will feel good and extremely rewarding. But when you remove it, it's really fucking bleak for a long time until your brain recovers and builds new dopamine pathways that aren't based on getting high.
In comparison, alcohol is much easier in some ways, but harder in others. Alcohol withdrawal lasts less long. It's unpleasant, and you get sweaty, with an increased heart rate, and struggle to sleep, but it's over quicker. If you are dependent on alcohol, then it can be dangerous - you can have a seizure and die, so tapering or having other medication can help. But the body load and physical withdrawal is nothing like weed and is over much faster, then all you are left with is the desire for pleasure and relaxation, you don't get months of feeling physically sick and unable to sleep and unable to enjoy anything.
Weed withdrawal for the most part is not dangerous. It's just horrible and lasts for a long time.
