There are some technical advantages to SmallCheck (determinism, no need
to shrink etc.), but the main reason I prefer it is because it gives me more
confidence. With quickcheck, I know that it generated 100 tests, but
I've no idea what those tests are, and whether the RNG missed some
important corner cases. With SmallCheck I know that it tried *all* cases
up to certain depth, so it's much more reassuring. (Except for cases
when the notion of depth isn't that informative, like floating-point
numbers.)
