Asus Prime (phase-change thermal pad) vs Zotac Gaming (5-yrs warranty). Help me choose

Is 5yrs warranty enough reason to want a Zotac GPU over other brands (specifically ASUS GPUs) ?

Asus RMA is handled by RP Tech and therefore is shitty in India. Prefer gigabyte/zotac which have good reviews for RMA. Recent gigabyte cards have 4 years of warranty
