Minecraft combat system?

Which of these minecraft combat systems do you find better

All have advantages and disadvantages!

I think 1.16 is cool

because there's a lot of new things

1.16, or Die Combat Snapshots

Since you could still block with the sword and had no delay

There's no difference between the combat system of 1.15 and 1.9.

1.9 is better for PvP and 1.8 for PvE
