Worth learning Score Editor for printout or 3rd party software bettereasie?

Hi,
I can either start seriously checking out the Score Editor for lead sheets and more involved printing of music... or get Sibelius or Finale and use those. I am not familiar with any of these - as I haven't started printing out music - but feel it's time.
I'd prefer just to stay in my all in one Logic Studio - but not sure if it's worth it in the big picture. (as in - if 3rd party software is easier/better by far - and most Logic people use those - why waste the time learning Score Editor in Logic?).
Any of you use the Score Editor for printing out scores, lead sheets? Whatdya think?
Thanks in advance.
