I'd argue for a couple of horrendous wonders:
Angkor Wat - There are a couple of reasons for why its a bad wonder. firstly it comes at a time where you should have the best tiles of all of your cities, making its main effects of lowering new tiles cost near irrelevant. It takes a whopping 400 production, which at a time where your best cities might pump out 30-35 hammers per turn is way to expensive for +1 culture and 1 GE point (you should not be far off workshops either, which give a GES slot instead). The AI also loves this wonder, so unless you're ahead in tech or have insane production/GE it might simply fail to build it. But the worst feature of the wonder is that it comes at the same tech as universities, which should be built as fast as you can to stay relevant in the science game (atleast om Immortal and Deity).
CN Tower - It just so irrelevant. 1 pop means nothing in the late game, and the +1 happiness per city is instantly lost do to the pop gain. A freebroadcast tower in each city is also worth little, as great musicians are much better at culture-bombing rather than takes Great work slots. The only time i can see this wonder useful is if you're goin for a culture victory eith freedom, as media culture is a rather strong tenet. But then again, if you're going for media culture why have you not built a broadcast tower already?
Cristo Redentor - AI loves it, the social policy reduction cost is so minor this late in the game, and +5 culture i also nothing at this point. Also comes at the same tech as research labs, which yet again is top priority for science.
Pentagon - Just like Cristo, the bonus is so minor at this point, as you'll only upgrade units a max of twice at the point its attainable, usually the game will end before you can do this.
Its still expensive and the GM points are useless at this stage.
Uffizi - just a very weak GA wonder. The lourve gives the same bonuses a bit lates but with an extra Slot for great works, and comes as the bonus for exploration, which is a much better social policy tree to go into. The sistine Chaptel might not have the free artist, but the +25% culture is amazing for any empire, not to mention how it does not requice any social policy trees adn is cheaper. Uffizi is also built like crazy by the AI since it loves to go down Aesthetics.
Red Fort - it looks nice, Ill give it that, but the 25% bonus to defensive buildings is very low at this point, unless you're playing babylon possibly. Its also pretty expensive and the GS point is jsut not that strong anymore.
Statue of Zeus - AI loves it, its expensive for early game and the bonus helps only a few millitant early game civs like the Huns or Zulu. The heroic epic is a pure upgrade that comes at a time where infastructure is so extremely important as the statue. Also requires Honor which is horrible as a starting policy tree unless you're someone who reasonably can and should pump out early game units like Germany or Aztec.
Taj Mahal - although the Happiness is nice and a golden age is not disliked, its just too expensive and the happiness can quicker be gained by making two zoos instead.
