Personally: (a) There are only 3 structures that can be bought to go in the water, the waterslide is the most profitable per hour for both short and long collection times, but the ROI time is huge, to pay for the purchase, admin staff and energy, optional upgrades, purchase of sea regions, takes a month or two of collections before returning a net profit. BUT the time-limited Pirate Ship (max 3) has an even higher profitability per cell space, its the best use of water space and as of 62 builds there are not yet any further water structures - standard or special, so when my game crashed and I started again, I made a point of grabbing the maximum 3 Pirate Ships. (b) Even tho they keep offering additional (LARGE) buildings, both standard and special, there are only 8 regions to purchase which initially seems like a large space, but as you level up it gets very crowded. So when you need a fully upgraded 25-cell power plant per 3 high-end structures, that means a quarter of your island space will be used just for energy plants. SO the time-limited Nano Generator that gives just over 3 times the power output (max upgrades) for the same space. ie. 5 maxed out Nano's gives you 8850 energies in 125 cell spaces (add the wind powers and you have 10,580 energies from a 15th of the island space. So I grabbed 5 Nano's.

Everything else I believe is aesthetics and profitability, but these two items give unique benefits un-equaled by any future offerings. So I would "absolutely not pass on" these structures.
