7.1 to 7.2 upgrade question

Hi there.

 

As I'm slowly getting used to FreeBSD (again), I recently upgraded three
boxes to 7.2-RELEASE.  Two of them were running 7.1-RELEASE and one was
running 7.2-RC2 ..

 

Anyways, I used freebsd-update to upgrade - in my previous experiences I
would have to do a "make world" etc. etc.  

 

Which method is most preferred - source or binary upgrading?  I don't mind
source upgrading but is it really necessary anymore if using freebsd-update
on a regular basis?

 

Thanks,

 

Paul
