Had a 3070 Palit, great though it was, now however, I wouldn't buy Palit/GW due to possible RMA ballaches with customs forms to fill and return post charges from Asia after the first yr of warranty is up.
Zotac I think still has UK RMA centre so that would be my choice of the three.
Longest warranty of any vendor too, 3 years standard and 5 if you register within 30 days.
