Replying to ARG vs LL2

I was wondering if anyone skied both and could compare them(189 LL2, not 179).  For next year I need a jib pow ski and decided that getting a medium flex instead of super soft would be worth it for larger cliffs.  Heres what I was guessing each would be better at:  Park:LL2s much better(for fun...not goin to be a park ski).  Breakable crud:ARGs.  Large cliffs ARGs.  Weight LL2s(arent they like 9lb a pair?).  Cascade wet snow probably ARGs, and groomers(mostly low angle ones)LL2s.  Whichever I get will be mounted with jesters(LL2s at here here here, or ARGs about -3 from center)
