I've had the misfortune of several alcoholic roommates, and it's disturbing. They'll yell at you, threaten you, get emotional, violent, cry, the whole works, and then deny it all the next morning.
In contrast, every regular marijuana user I've known long enough to form a judgement about their habit is very inoffensive to the people around them. It doesn't seem to bleed out into their work and emotional lives as much.
Heavy marijuhana smokers can show some or all of that traits, too.
But in general if I would have to chooss between a heavy pot smoker and a heavy drinker as roommate, I probably would "prefer" the average marijuanna user

The evidence doesn't support marijuana being more dangerous than alcohol. https://en.wikipedia.org/wiki/Drug_harmfulness#/media/File:D... Alcohol is moderately more habit forming, and several orders of magnitude more dangerous.
