i beat this game that was fun .. Dance . never playing game this harder since nier out ..

So i beat this game like 2/3 days ago .. i clear all side quest and main story ..
and my question is
it worth to play 2nd run to chek another ending ..? or just chek youtube to save my time ..? (i can do boss run thoo to save my time and chek the ending since this game isn't that hard either )
