Question: if you had to say, swim across a lake, would you prefer the water be crystal-clear or completely black?

Not really swim across the lake, just swim in it. By crystal clear, I mean clear; you can see all the way to the bottom, including all the seaweed and sturgeon and shit. Or you can choose for it to look normal and be completely black and you can't see the bottom at all. Both suck, in my opinion?
