Best Assets for sky/weather/ocean

What should be the best assets for a big realistic game?

- Unistorm: I own this one (last madness sale - I talk more about this one since i have it). Complete weather and day night solutions. The effects are average(improved in 2.x but no special compared to other). Support sometime miss my messages... The codes are not really organized for someone who work in corporate for a long time like me.
Integrate with Ceto: Ocean System for a water solution. Have something unique like the farm growing system or moon phase. Though it is not really a big deal.

- Sky Master Ultimate: Said by a lot of people to be the best out there. A completed weather, day night, ocean solution. The effects are maybe the best out there. Any drawback guy? I don't want to buy this since I think ceto ocean is better solution for ocean.

- Time of Day: only sky solution. Quite expensive compared to other.

- TENKOKU Dynamic Sky: sky and weather system. I don't know much about this one.

- Ceto Ocean: (I own this one as well) I think this is the best standalone ocean solution out there. The effects are just stunning.

- SUIMONO Water System: it maybe looks even better than ceto in some situation but it is too heavy, seriously fps drop is too much.

Please give your opinions.

 

I've barely scratched the surface, but trueSKY by Simul seems pretty darn sweet.
