Quiet night is very forceful (I love it). Even if it faded a little I think it would be quite flavorful.
The problem with the faded latakia is that the orientals behind it start to show up and the blends were blended with latakia, not those various oriental components. They can become an amalgamation. What I find is that the more latakia, the less well it ages for this reason.
I have had experience with 10 year old QN and it wasn't great. I had a 12 or 13 year old tin of daVinci, which I love fresh, that was absolutely atrocious.
Meanwhile, blends like Squadron Leader seem to age exceptionally well and it does not have a lot of latakia.
Obviously, YMMV but it's something to keep in mind.
Edit to add that if you prefer strong latakia, you want it fresh. There is a sweet spot for melding flavors of 3-5 years where you still get your strong latakia. It seems, to me, that at about 5-7 years the decline begins.
