I think Biology-Molecular is the easiest, having taken it and Chemistry.
Although the curve for Biology-M is one of the least generous of the sciences, I think it is easier to get a 780-800 on it than Physics and Chemistry. I am not sure about Biology-Ecological, as I really dislike Ecology.

Let's see...

I, right off the bat, would not recommend chemistry, because it really is an annoying combination of math and concepts that would be quite hard (well, annoying) to well study. But then again, whatever floats your boat.

Physics is, from what I've heard, not a difficult exam to study and the curve is quite generous, but it does take a very math-oriented person to do well in physics. Just keep that in mind.

Biology is the one that I would recommend the most, because its pure memorization. There are no tricks about it. Just read, memorize, and take the test. It's the simplest one (unless your brain cycles through mathematical theories every minute of the day). In my experience, ecology is much simpler than molecular. There's more molecular to be studied and ecology is a lot of common sense.

IMHO, biology > physics > chemistry.

There is almost NO math whatsoever on the Chemistry test. MV=MV, Graham's law, Combined Gas Law, G = H - T*S (Gibbs), PV=nRT, and a few others, are literally all you will ever have to know.

Protagonizer

For Biology, if you read and assimilate the Barron's SAT II prep book, optionally supplement it with the PR book, and take a few practice tests, you will be more than set to score 750+. However, I find that it is generally harder to score an 800 on Bio than other the other science subject tests due to the far less lenient curve.

Biology (E) FTW!
