i use a notebook as mousepad so i dont care
steelseries qck edge
qck is the most popular pad, very affordable main problem was bad edges, edge model solves this problem perfectly.
i have some generic mousepad with military camo pattern because it was big af and i needed for low sense abuse
razer gigantus v2 medium (i play high sens)
xraypads aqua control2
had steelseries qck+ after 1 month on 1.3 sens you can throw it away
QCK heavy, its cheap and has a very neutral glide, they wear out fast though so replace it every few months.
