Oh dear - I couldn't list them (detergent and fabric softener is my thing, I actually love experimenting with the scent combos).
I have 5 different Lenor's and 6 or 7 different Comfort's 
. That's besides those Unstoppable scent bead things. Not loyal to a softener or detergent at all - will use all of them, depending on what I am washing etc.
Most these days are pretty strong, so any you chose you will be able to smell (it's more the "getting used" to the same smell for why you stop smelling it).
I usually use less powder, as I have to be really careful with dosing (very soft water area and have a Samsung shit Eco Bubble).
I will put a bit more in if I think that particular load/cycle will handle it .
I really can't pick a fave softener (there are more I like than dislike), but off hand one of my more favoured ones is Comfort Blueberry and Jasmine.
One thing I can say from many years experimenting, the soap/softener combo has a massive impact on what the final smell is, the same softener can end up smelling totally different, depending on what detergent it's used with.
