There are only 4 brands making 3.5" drives today, so "top 3" is probably not useful. Here they are, more-or-less in order of reliability based on recent BackBlaze stats.
HGST (owned by WD, consistently highest reliability)
Toshiba (small BackBlaze pool, so stats show higher variability)
Seagate (2nd largest, seems to have upped their quality the last couple years)
Western Digital (largest one, seems to have become less attentive to quality lately)
