The different cutaways on the two basses on this thread are the original Small Standard shape (brought back for the Brown Bass series) and the modern SC shape.
For the scale lengths, I can compare only apples and oranges - a long scale fretless Epic (set neck) and a medium scale fretted Spoiler (neck through).
Anyway - if you've only played long scale until now, you might be surprised by the amount of sustain that the shorter scale Alembics are capable of.
