"Pascal lite is to pascal as expanse is to eth"

Not the case here. Whereas EXP is wholly ectypal to ETH, PASL is a few steps in front of PASC. Account trading site is one example, PASL github has many more commits than PASC. Also, as I inderstood from Slack, something which will make acquiring accounts easier is in the works.  I'm sure much more will come.

PASL is simply better and more creative than PASC.
