The old twin towers were iconic for the various reason and largely because of their (boring) design and what they represented. It was the symbol of the American capitalist system and it was an iconic structure.

You never really see 1WTC in iconic imagery. It is very non-descript and does have the bold (almost offensive) impact that the old twin towers had.

ESB was American elegance while the old WTC was American brute arrogance and both complemented each other at opposite points of the skyline.

1WTC is designed by committee. You get a non-offensive forgetful structure. It is tall but nobody notices it aside from the hallowed spot where it sits.

Back to the OP question - ESB will always have the crown. I find it offensive any towers even attempt to beat out the ESB in height as it is impossible to reproduce the elegance ESB has in today's time - nothing will compare.
