The AU brings some new/improved features so, in that sense it's 'worth' it.
if I understand correctly, the majority of the issues stem from older hardware. If your laptop is relatively new, you're unlikely to experience any issues. Ensure you back up just to be 100% sure.
There;s still plenty of time for the update, so it won't hurt to wait it out a little longer for a smoother install - unless any of the improvements/new additions are needed at the moment.
As with any substantial update, a clean install of the OS is recommended - but not 100% necessary.
