Favourite kind of onion?

Red onions are the best onions because of their uses. If I see one more yellow onion in a salad, I am going to cry, and it's because it's a yellow onion, not out of sadness. Yellow onions that are raw are disgusting. Yellow onions are only good when sautèed. A red onion that is raw tastes amazing. Additionally, a raw red onion in a sandwich can complement the sandwich, but a yellow onion will fall flat.

Depends on the application: If in a soup/stew-yellow onions. if in a salad-red or sweet. If in a stir fry-yellow or green. Generally, yellow onions can be rather strong, particularly that which is called a Spanish onion. While red can be strong as well, it is more desirable in a salad or on a burger. Green onions are milder in taste and quite versatile. And sweet onions like Vidalias, can be eaten like an apple.

I like green onions to just eat plain.

I cook with all types of onions...

White onions in Mexican food.

Red onions raw on burgers or salads

Yellow onions for most other things.

I also sometimes use shallots and leeks for a milder onion flavor.

For the record, there are no ranch onions, hard onions, or sour onions.

There ARE green, yellow, red, sweet (vidalia), shallots, pearl onions, and a few others

It depends on what I'm going to use it for. If it's raw on a hamburger or in salad, red onion. For onion rings or onion soup, sweet onions are better. Cipolle borettane for pickling in balsamic vinegar.
