Please name some of the power metal albums that you think can stand with most of the albums from our top thrash lists.
80s power/speed metal easily stands up against the thrash greats. I wouldn't call it better or worse than thrash but like others have said, I'd have a hard time picking a preferred genre out of heavy, power, thrash, doom, black, and death metal. Each of those sub-genres have spawned some of the finest examples of heavy metal in the history of the genre.
Anyways, as far as power metal goes, these albums are among the best:
Fates Warning - Awaken the Guardian
Omen - Battle Cry
Helstar - Nosferatu
Liege Lord - Burn to My Touch
Attacker - Battle at Helm's Deep
Blind Guardian - Tales from the Twilight World
Brocas Helm - Black Death
Helloween - Keeper of the Seven Keys Part I
Agent Steel - Skeptics Apocalypse
Adramelch - Irae Melanox
