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".
