bottle trap design differences?

We're installing a vessel sink on a floating countertop. The drain plumbing will be visible. We'd like to install a bottle trap, but I have read that most are not code compliant.

However, there appears to be two different types of bottle traps. One type has both horizontal and vertical pipes of approximately the same diameter while the second type, called a basin siphon, has a much larger container to which both the vertical and horizontal pipes connect.

Is this second type simply an enclosed "J" trap? And is it better than the first type?

TIA
