Elsewhere I told of my amazement when I tried the "Adelphi" glass in a head to head with a Bugatti Kelch.
I like the Bugatti, I also like what I call the Signatory, which I name thus as most of mine have the "Signatory" IB name on them. But so far, I think I preferred the Glencairn. Mainly because of its solid build and the way it sits in the hand.
To be honest, I haven't found much difference between the nosing performance of each of these glasses, although if anything, the slightly larger "Classic Malts" glass is probably the best, but I only have a couple of these in my own drinks cabinet.
But all of that is now history, as they say.
At the Munich whisky festival I came across the glass commissioned by "Adelphi". A very well-renowned IB some of whose bottlings are legendary.
A few asked me to take a picture, so here you go:

A slightly better version of the pic.

From left to right:
Adelphi, Classic Malts, Bugatti, Signatory (in this case Glenmorangie), Glencairn
You will immediately see that the Adelphi is far and away the largest, it also has a rim which curves slightly outward.
The nosing performance of this glass is so good, it is almost incomparable to the others. So far I have allowed a few people in The Arc to use this alongside any other glass of their choice and every time they have been astonished at the difference.
Here it is in close-up:
