None of those listed; I've seen games where the Oracle expired before being built -- in fact, I think that I've only seen one or two other wonders expired ever.
Eiffel & Manhatten are hard to justify. I've never built a police station & the need to Woman's Suffrage is very small -- almost nil even in Democracy. Rehome the units to size two "production" cities and have JSB -- what unhappiness problem? Bloodthirsty play has very little use for Apollo (600 shields for a map?) OCC (one city) won't get a lot of value out of JSB, Pyramids, Cfc, etc.
Most of the wonders are nice, very nice, or terrific -- so I'll try to build most of them.
Great Library is a terrific wonder -- especially for four player multiplayer (say 4) games. It is also "nice" for newbies. Once a player discovers the value of trade, GL's luster fades.
