Compared to the new and modern GPT, it is. :-)
However, if you keep using the "old" way, it will still be
supported and will not confuse either BIOSes or other systems
that are maybe installed on your machine.

I'm also not aware of any performance issues.

According to the article, there are some BIOSes that don't
seem to like disks not containing a "DOS primary partition"
to start their boot chain. While this may be true, I have
never experienced it.
For maximum security, you can use the "old" approach of
using fdisk + disklabel (creating slice, creating partitions
within slice). This also delivers most compatibility for
other systems, if it should be needed, e. g. in a multiboot
