Nice thread!
I was thinking the same thing a couple of days back.
I think both Wimbledon & USO trophy are the prettiest. While Wimbledon trophy looks more Royal because of the
Golden colour & Pineapple on the top, the USO trophy looks a beautiful piece of Silverware! I find the shape and the handles of USO one a bit more aesthetic.
Then comes the RG Cup, which looks really classy as well with the small handles shaped like Wings of a Swan!
The AO Cup looks a bit dull IMO. The AO Women's Trophy looks much better and elegant.
But I've noticed one thing. That outside of Slams, the lesser the prestige of a tournament, the better looking it's trophy is!
I guess it's kind of over compensation they try to do.
For eg. the Acapulco, Doha, and Dubai trophies are much better than say...Indian Wells and Cincinnati trophies.
