Razer Deathadder or Logitech G502 Hero?

I mainly play Minecraft

Then a billo mouse is enough

The Deathadder is more known for being a PvP player, with the G502 it looks more for the people who build a lot. You have to decide for yourself. If the shops are open again, you can go and test the mice and see which one you like more

Ideally, test, otherwise think carefully about which shape you like better. One can't say in general which mouse is "better".
