The wonder I love starting next to the most is Zhangye Danxia because you don't need to work it for the bonus; you just start accumilating 2 great general and 2 great mercant points from turn 1 without needing to build either district (almost means you will likely be the first 2 generals and merchants before nayone else get's their first), and especially as a more naval/harbour focused player; I will never say no to free great merchants and generals which I otherwise would never get! Mount Roraima is a close second to Zhangye Danxia for the sheer amount of faith and science. (As Bite said; anything that gives you faith early on is defeinatly worth investing in for your pantheon.) Worst, as for most of us, is the White Cliffs of Dover which is a shame for me as a Brit. It's always in such an akward place where you can never get the most out of it and always feels like a waste of space. I've never found it in a place that gives you ample food in order to sacrifice 2 citizens to work it, and in costal cities you really need as much land as possible for districts; let alone the fact the to me it's a eyesore too; just 2 flat and featureless yellowly tiles (should be hilly and green at the very least) with a slightly different colour for the cliffs... I am going to bet, that whatever the Bermuda Triangle does in the upcoming DLC (which I think will be something bad), it will still be better then owning the White Cliffs of Dover.
