DVD-R/RW over DVD+ advantages? Does it make a difference in 2017/2018?



A decade ago, DVD-R/RW was for compatibility. DVD+R/RW had read support but several advantages for writing and 817.4 instead of 140.6 kHz of wobble frequency.
DVD-R/RW contained recorder information.

For today’s disc drives, does it make any difference?
Does the buffer underrun scar (tiny gap that -R/RW and CDs suffered from but compensated by error correction) still exist on modern drives?

What are the practical differences in today’s world?

I am glad that both exist, however. HD-DVD,CD-RW×32 and DVD-RAM×12 should come back please.
