I'm sorry if you picked the wrong mods for you. You've got to find the right ones for you, and it's possible you don't need any at all. Personally I'm typically most interested in mods that bring quality of life improvements, such as UI improvements. Especially Bethesda's games on PC are guilty of having a horrible UI. It works well on consoles, but not so much on PC. Mods fix that, and something that was really painful a lot of the time suddenly becomes much more bearable. Even small things like that improve my experience by quite a lot, but if I want something else, it's available. New content and graphics improvements are the two main things coming to my mind right now.
